Struct FixedWidthUint

pub struct FixedWidthUint<'a, T: FixedWidthEncoding + ?Sized>(/* private fields */);

A fixed width encodable unsigned integer

Trait Implementations

impl<T: FixedWidthEncoding> CompactEncoding<<T as FixedWidthEncoding>::Decode> for FixedWidthUint<'_, T>

fn encoded_size(&self) -> Result<usize, EncodingError>

The size in bytes required to encode self.

fn encode<'a>( &self, buffer: &'a mut [u8], ) -> Result<&'a mut [u8], EncodingError>

Encode self into buffer returning the remainder of buffer.

fn decode(buffer: &[u8]) -> Result<(T::Decode, &[u8]), EncodingError>

where Self: Sized,

Decode a value from the given buffer of the type specified by the Decode type parameter (which defaults to Self). Returns the decoded value and remaining undecoded bytes.

fn to_encoded_bytes(&self) -> Result<Box<[u8]>, EncodingError>

Encode self into a Vec<u8>. This is just a helper method for creating a buffer and encoding to it in one step.

fn create_buffer(&self) -> Result<Box<[u8]>, EncodingError>

Create an empty buffer of the correct size for encoding self to. This is just a helper method for: encoding to it in one step.

fn encode_with_len<'a>( &self, buffer: &'a mut [u8], ) -> Result<(&'a mut [u8], usize), EncodingError>

Like CompactEncoding::encode but also return the number of bytes encoded.

fn decode_with_len( buffer: &[u8], ) -> Result<(Decode, &[u8], usize), EncodingError>

where Decode: Sized,

Like CompactEncoding::decode but also return the number of bytes decoded.

impl<'a, T: Debug + FixedWidthEncoding + ?Sized> Debug for FixedWidthUint<'a, T>

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

Formats the value using the given formatter.
