Enum TypeStem

pub enum TypeStem<'a> {
    Root(RootType<'a>),
    Tuple(TupleSpecifier<'a>),
}

A stem of a Solidity array type. It is either a root type, or a tuple type.

Examples

let stem = TypeStem::parse("uint256")?;
assert_eq!(stem.span(), "uint256");
assert!(matches!(stem, TypeStem::Root(_)));
assert_eq!(stem.as_root(), Some(&RootType::parse("uint256").unwrap()));

let stem = TypeStem::parse("(uint256,bool)")?;
assert_eq!(stem.span(), "(uint256,bool)");
assert!(matches!(stem, TypeStem::Tuple(_)));
assert_eq!(stem.as_tuple(), Some(&TupleSpecifier::parse("(uint256,bool)").unwrap()));

Variants

Root(RootType<'a>)

Root type.

Tuple(TupleSpecifier<'a>)

Tuple type.

Implementations

impl<'a> TypeStem<'a>

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

Parse a type stem from a string.

pub const fn as_root(&self) -> Option<&RootType<'a>>

Fallible conversion to a root type

pub const fn as_tuple(&self) -> Option<&TupleSpecifier<'a>>

Fallible conversion to a tuple type

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

Returns the type stem 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 TypeStem<'_>

fn as_ref(&self) -> &str

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

impl<'a> Clone for TypeStem<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TypeStem<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for TypeStem<'a>

fn eq(&self, other: &TypeStem<'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 TypeStem<'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.
