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 duplicate 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.

impl<'a> Eq for TypeStem<'a>

impl<'a> StructuralPartialEq for TypeStem<'a>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
