Struct FunctionType 

pub struct FunctionType<'a> {
    pub params: Box<[(Option<Id<'a>>, Option<NameAnnotation<'a>>, ValType<'a>)]>,
    pub results: Box<[ValType<'a>]>,
}

A function type with parameters and results.

Fields

params: Box<[(Option<Id<'a>>, Option<NameAnnotation<'a>>, ValType<'a>)]>

The parameters of a function, optionally each having an identifier for name resolution and a name for the custom name section.

results: Box<[ValType<'a>]>

The results types of a function.

Trait Implementations

impl<'a> Clone for FunctionType<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for FunctionType<'a>

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

Formats the value using the given formatter.

impl<'a> Default for FunctionType<'a>

fn default() -> FunctionType<'a>

Returns the “default value” for a type.

impl From<&FunctionType<'_>> for FuncType

fn from(ft: &FunctionType<'_>) -> Self

Converts to this type from the input type.

impl<'a> From<FunctionTypeNoNames<'a>> for FunctionType<'a>

fn from(ty: FunctionTypeNoNames<'a>) -> FunctionType<'a>

Converts to this type from the input type.

impl<'a> Parse<'a> for FunctionType<'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> Peek for FunctionType<'a>

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

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