Struct macroex::Bytes

pub struct Bytes(pub Vec<u8>);

Specialized extractor for Vec<u8> that additionally accepts a byte string literal.

Examples

let mut value: Vec<u8>;
Bytes(value) = quote!([49, 50, 51]).into_iter().extract()?;
assert_eq!(value, b"123");
Bytes(value) = quote!(b"456").into_iter().extract()?;
assert_eq!(value, b"456");

Tuple Fields

0: Vec<u8>

Trait Implementations

impl Debug for Bytes

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

Formats the value using the given formatter.

impl Default for Bytes

fn default() -> Bytes

Returns the “default value” for a type.

impl FromMacro for Bytes

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.
