Struct macroex::Byte

pub struct Byte(pub u8);

Specialized extractor for u8 that additionally accepts a byte char literal.

Examples

let mut value = 0u8;
Byte(value) = quote!(42).into_iter().extract()?;
assert_eq!(value, 42);
Byte(value) = quote!(b'@').into_iter().extract()?;
assert_eq!(value, b'@');

Trait Implementations

impl Clone for Byte

fn clone(&self) -> Byte

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Byte

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

Formats the value using the given formatter.

impl Default for Byte

fn default() -> Byte

Returns the “default value” for a type.

impl FromMacro for Byte

fn from_one(tt: TokenTree) -> Result<Self, Error>

This will be called if there is only one item

const PREFER_MANY: bool = false

Hint to All and similar extractors to disable length validation.

fn from_many(tokens: TokenStream) -> Result<Self, Error>

This will be called if there is more than one item.

fn peek(tt: &TokenTree) -> bool

Look ahead and determine parsability.

impl Hash for Byte

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Byte

fn eq(&self, other: &Byte) -> 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 !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToTokens for Byte

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.

impl Copy for Byte

impl Eq for Byte

impl StructuralEq for Byte

impl StructuralPartialEq for Byte
