Struct ConfigField

pub struct ConfigField {
    pub key: Option<String>,
    pub type_: Option<ConfigType>,
    pub mutability: Option<ConfigMutability>,
    /* private fields */
}

Declares a single config field (key + type)

Fields

key: Option<String>

(Required) The identifier for this config field. This key will be used to match overrides.

type_: Option<ConfigType>

(Required) The type of config values. Config values are verified against this layout at build time and run time.

mutability: Option<ConfigMutability>

Allowed sources for runtime overrides of this field’s value.

Trait Implementations

impl Clone for ConfigField

fn clone(&self) -> ConfigField

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigField

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

Formats the value using the given formatter.

impl<D> Decode<ConfigField, D> for ConfigField

where D: ResourceDialect,

fn new_empty() -> ConfigField

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 Default for ConfigField

fn default() -> ConfigField

Returns the “default value” for a type.

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

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 PartialEq for ConfigField

fn eq(&self, other: &ConfigField) -> 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 TypeMarker for ConfigField

type Owned = ConfigField

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 ConfigField

type Borrowed<'a> = &'a ConfigField

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: &<ConfigField as TypeMarker>::Owned, ) -> <ConfigField as ValueTypeMarker>::Borrowed<'_>

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