The Read trait provides a means of reading from byte streams.

Required methods

pub fn read(&mut self, buf: &mut [u8]) -> Result<usize, ParseError>[src]

Read a number of bytes into the provided buffer. The returned value is Ok(n) if a read was successful, and n bytes were read (n could be 0).

Provided methods

pub fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), ParseError>[src]

Read exactly the required number of bytes. If not enough bytes could be read the function returns Err(_), and the contents of the given buffer is unspecified.

pub fn read_u64(&mut self) -> Result<u64, ParseError>[src]

Read a u64 in little-endian format.

pub fn read_u32(&mut self) -> Result<u32, ParseError>[src]

Read a u32 in little-endian format.

pub fn read_u16(&mut self) -> Result<u16, ParseError>[src]

Read a u16 in little-endian format.

pub fn read_u8(&mut self) -> Result<u8, ParseError>[src]

Read a u8.

pub fn read_i64(&mut self) -> Result<i64, ParseError>[src]

Read a i64 in little-endian format.

pub fn read_i32(&mut self) -> Result<i32, ParseError>[src]

Read a i32 in little-endian format.

pub fn read_i16(&mut self) -> Result<i16, ParseError>[src]

Read a i16 in little-endian format.

pub fn read_i8(&mut self) -> Result<i8, ParseError>[src]

Read a i32 in little-endian format.

Implementors

impl Read for ContractState[src]

pub fn read_u64(&mut self) -> ParseResult<u64>[src]

Read a u32 in little-endian format. This is optimized to not initialize a dummy value before calling an external function.

pub fn read_u32(&mut self) -> ParseResult<u32>[src]

Read a u32 in little-endian format. This is optimized to not initialize a dummy value before calling an external function.

pub fn read_u8(&mut self) -> ParseResult<u8>[src]

Read a u8 in little-endian format. This is optimized to not initialize a dummy value before calling an external function.
