Struct ConstInteger 

pub struct ConstInteger<const V: u128>(/* private fields */);

A constant u128 integer of value V. Must match V and also has Default implemented to create a LiteralInteger with value V.

let mut token_iter = "foo".to_token_iter();

let parsed = <OrDefault<u32, ConstInteger<1234>>>::parser(&mut token_iter).unwrap();
assert_tokens_eq!(parsed, "1234");

Implementations

impl<const V: u128> ConstInteger<V>

pub const fn value(&self) -> u128

Get the value.

pub fn into_inner(self) -> LiteralInteger

Deconstructs self and gets the LiteralInteger

Trait Implementations

impl<const V: u128> Clone for ConstInteger<V>

fn clone(&self) -> ConstInteger<V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const V: u128> Debug for ConstInteger<V>

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

Formats the value using the given formatter.

impl<const V: u128> Default for ConstInteger<V>

fn default() -> ConstInteger<V>

Returns the “default value” for a type.

impl<const V: u128> Parser for ConstInteger<V>

fn parser(tokens: &mut TokenIter) -> Result<ConstInteger<V>, Error>

The actual parsing function that must be implemented. This mutates the tokens iterator directly. It should not be called from user code except for implementing parsers itself and then only when the rules below are followed.

impl<const V: u128> ToTokens for ConstInteger<V>

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

Write &self to the given TokenStream.

fn to_token_iter(&self) -> TokenIter

Convert &self into a TokenIter object.

fn into_token_iter(self) -> TokenIter

where Self: Sized,

Convert self into a TokenIter object.

fn to_token_stream(&self) -> TokenStream

Convert &self into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self into a TokenStream object.

fn tokens_to_string(&self) -> String

Convert &self into a String object. This is mostly used in the test suite to compare the outputs. When the input is a &str then this parses it and returns a normalized String.
