Struct wast::Id

pub struct Id<'a> { /* private fields */ }

An identifier in a WebAssembly module, prefixed by $ in the textual format.

An identifier is used to symbolically refer to items in a a wasm module, typically via the Index type.

Implementations

impl<'a> Id<'a>

pub fn name(&self) -> &'a str

Returns the underlying name of this identifier.

The name returned does not contain the leading $.

pub fn span(&self) -> Span

Returns span of this identifier in the original source

Trait Implementations

impl<'a> Clone for Id<'a>

fn clone(&self) -> Id<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Id<'_>

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

Formats the value using the given formatter.

impl<'a> From<Id<'a>> for Index<'a>

fn from(id: Id<'a>) -> Index<'a>

Performs the conversion.

impl<'a> Hash for Id<'a>

fn hash<H: Hasher>(&self, hasher: &mut H)

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl<'a> Parse<'a> for Id<'a>

fn parse(parser: Parser<'a>) -> Result<Self>

Attempts to parse Self from parser, returning an error if it could not be parsed.

impl<'a> PartialEq<Id<'a>> for Id<'a>

fn eq(&self, other: &Id<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Peek for Id<'_>

fn peek(cursor: Cursor<'_>) -> bool

Tests to see whether this token is the first token within the Cursor specified.

fn display() -> &'static str

Returns a human-readable name of this token to display when generating errors about this token missing.

fn peek2(cursor: Cursor<'_>) -> bool

The same as peek, except it checks the token immediately following the current token.
