Enum StringSelector

pub enum StringSelector {
    StringPattern(String),
    ExactMatch(String),
    // some variants omitted
}

StringSelector is an union defining different ways to describe a pattern to match strings against.

Variants

StringPattern(String)

This is a provided string that defines a pattern to match against. The parser treats asterisks (*), colons (:) and backslashes () as special characters.

If you wish to match against literal asterisks (*), they must be escaped. If you wish to match against literal backslashes (), they must be escaped. If you wish to match against literal colons (:), they must be escaped.

eg: abc will match any string with the exact name “abc”. eg: a* will match any string with the exact name “a*”. eg: a\* will match any that starts with exactly “a". eg: a* will match any string that starts with “a”. eg: ab will match any string that starts with a and ends with b. eg: ab*c will match any string that starts with a and ends with c, with b in the middle.

In addition, the “**” literal is treated as a special sequence that may match multiple levels in a component selector only. See |ComponentSelector| for details.

ExactMatch(String)

Implementations

impl StringSelector

pub fn ordinal(&self) -> u64

pub fn unknown_variant_for_testing() -> StringSelector

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Clone for StringSelector

fn clone(&self) -> StringSelector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StringSelector

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

Formats the value using the given formatter.

impl<D> Decode<StringSelector, D> for StringSelector

where D: ResourceDialect,

fn new_empty() -> StringSelector

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<StringSelector, D> for &StringSelector

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 StringSelector

fn eq(&self, other: &StringSelector) -> 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 StringSelector

type Owned = StringSelector

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 StringSelector

type Borrowed<'a> = &'a StringSelector

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

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