Struct AttributePermissions

pub struct AttributePermissions {
    pub read: Option<Box<SecurityRequirements>>,
    pub write: Option<Box<SecurityRequirements>>,
    pub update: Option<Box<SecurityRequirements>>,
}

Specifies the access permissions for a specific attribute value.

Fields

read: Option<Box<SecurityRequirements>>

Specifies whether or not an attribute has the read permission. If null, then the attribute value cannot be read. Otherwise, it can be read only if the permissions specified in the Permissions struct are satisfied.

write: Option<Box<SecurityRequirements>>

Specifies whether or not an attribute has the write permission. If null, then the attribute value cannot be written. Otherwise, it be written only if the permissions specified in the Permissions struct are satisfied.

update: Option<Box<SecurityRequirements>>

Specifies the security requirements for a client to subscribe to notifications or indications on a characteristic. A characteristic’s support for notifications or indiciations is specified using the NOTIFY and INDICATE characteristic properties. If a local characteristic has one of these properties then this field can not be null. Otherwise, this field must be left as null.

This field is ignored for Descriptors.

Trait Implementations

impl Clone for AttributePermissions

fn clone(&self) -> AttributePermissions

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AttributePermissions

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<D> Decode<AttributePermissions, D> for AttributePermissions

where D: ResourceDialect,

fn new_empty() -> AttributePermissions

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl<D> Encode<AttributePermissions, D> for &AttributePermissions

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl Hash for AttributePermissions

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for AttributePermissions

fn cmp(&self, other: &AttributePermissions) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AttributePermissions

fn eq(&self, other: &AttributePermissions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for AttributePermissions

fn partial_cmp(&self, other: &AttributePermissions) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TypeMarker for AttributePermissions

type Owned = AttributePermissions

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for AttributePermissions

type Borrowed<'a> = &'a AttributePermissions

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<AttributePermissions as TypeMarker>::Owned, ) -> <AttributePermissions as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
