Struct CIntegerLiteralCodec 

pub struct CIntegerLiteralCodec;

Decodes non-negative C integer literal fragments.

This codec accepts decimal literals such as 123, octal literals such as 0123, and hexadecimal literals such as 0x123 or 0X123. It trims surrounding whitespace and returns a u64.

Implementations

impl CIntegerLiteralCodec

pub fn new() -> Self

Creates a C integer literal codec.

Returns

A stateless C integer literal codec.

pub fn decode(&self, text: &str) -> CodecResult<u64>

Decodes a C integer literal into a u64.

Parameters

• text: C integer literal text.

Returns

Parsed integer value.

Errors

Returns CodecError::InvalidInput when the input is empty, lacks digits, or overflows u64; returns CodecError::InvalidDigit when a character is not valid for the detected radix.

Trait Implementations

impl Clone for CIntegerLiteralCodec

fn clone(&self) -> CIntegerLiteralCodec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CIntegerLiteralCodec

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

Formats the value using the given formatter.

impl Decoder<str> for CIntegerLiteralCodec

fn decode(&self, input: &str) -> Result<Self::Output, Self::Error>

Decodes a C integer literal into a u64.

type Error = CodecError

Decoding error type.

type Output = u64

Decoded output type.

impl Default for CIntegerLiteralCodec

fn default() -> CIntegerLiteralCodec

Returns the “default value” for a type.

impl PartialEq for CIntegerLiteralCodec

fn eq(&self, other: &CIntegerLiteralCodec) -> 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.
