Struct 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 Clone for Bytes

fn clone(&self) -> Bytes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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.

fn peek(tt: &TokenTree) -> bool

Look ahead and determine parsability.

impl Hash for Bytes

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 Bytes

fn eq(&self, other: &Bytes) -> 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 ToTokens for Bytes

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.
