Struct TupleSpecifier

pub struct TupleSpecifier<'a> {
    pub span: &'a str,
    pub types: Vec<TypeSpecifier<'a>>,
}

A tuple specifier, with no array suffixes. Corresponds to a sequence of types.

The internal types are all TypeSpecifier, and may be arbitrarily complex.

Examples

let spec = TupleSpecifier::parse("(uint256,uint256)")?;
assert_eq!(spec.span(), "(uint256,uint256)");
assert_eq!(spec.types.len(), 2);
assert_eq!(spec.types[0].span(), "uint256");

// No array suffixes. Use `TypeSpecifier` instead.
assert!(TupleSpecifier::parse("(uint256,uint256)[]").is_err());

Fields

span: &'a str

The full span of the tuple specifier.

types: Vec<TypeSpecifier<'a>>

The internal types.

Implementations

impl<'a> TupleSpecifier<'a>

pub fn parse(input: &'a str) -> Result<Self>

Parse a tuple specifier from a string.

pub const fn span(&self) -> &'a str

Returns the tuple specifier as a string.

pub fn try_basic_solidity(&self) -> Result<()>

Returns true if the type is a basic Solidity type.

Trait Implementations

impl AsRef<str> for TupleSpecifier<'_>

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a> Clone for TupleSpecifier<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TupleSpecifier<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for TupleSpecifier<'a>

fn eq(&self, other: &TupleSpecifier<'a>) -> 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<'a> TryFrom<&'a str> for TupleSpecifier<'a>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &'a str) -> Result<Self>

Performs the conversion.
