}Expand description
Defines how primitive values are to be read from Self.
Required methods
fn read_u8(&mut self) -> Result<u8, DeserializationError>
fn read_u8(&mut self) -> Result<u8, DeserializationError>
Returns a single byte read from self.
Errors
Returns a DeserializationError error the reader is at EOF.
fn read_u16(&mut self) -> Result<u16, DeserializationError>
fn read_u16(&mut self) -> Result<u16, DeserializationError>
Returns a u16 value read from self in little-endian byte order.
Errors
Returns a DeserializationError if a u16 value could not be read from self.
fn read_u32(&mut self) -> Result<u32, DeserializationError>
fn read_u32(&mut self) -> Result<u32, DeserializationError>
Returns a u32 value read from self in little-endian byte order.
Errors
Returns a DeserializationError if a u32 value could not be read from self.
fn read_u64(&mut self) -> Result<u64, DeserializationError>
fn read_u64(&mut self) -> Result<u64, DeserializationError>
Returns a u64 value read from self in little-endian byte order.
Errors
Returns a DeserializationError if a u64 value could not be read from self.
fn read_u128(&mut self) -> Result<u128, DeserializationError>
fn read_u128(&mut self) -> Result<u128, DeserializationError>
Returns a u128 value read from self in little-endian byte order.
Errors
Returns a DeserializationError if a u128 value could not be read from self.
fn read_u8_vec(&mut self, len: usize) -> Result<Vec<u8>, DeserializationError>
fn read_u8_vec(&mut self, len: usize) -> Result<Vec<u8>, DeserializationError>
Returns a byte vector of the specified length read from self.
Errors
Returns a DeserializationError if a vector of the specified length could not be read
from self.
fn read_u8_array<const N: usize>(
&mut self
) -> Result<[u8; N], DeserializationError>
fn read_u8_array<const N: usize>(
&mut self
) -> Result<[u8; N], DeserializationError>
Returns a byte array of length N reade from self.
fn has_more_bytes(&self) -> bool
fn has_more_bytes(&self) -> bool
Returns true if there are more bytes left to be read from self.
