Struct concordium_std::test_infrastructure::TestParameterCursor

pub struct TestParameterCursor<'a> { /* private fields */ }

👎Deprecated since 8.1.0: Deprecated in favor of concordium-smart-contract-testing.

Test parameter cursor. Should not be constructed directly, use TestReceiveContext or TestInitContext.

Trait Implementations

impl<'a> AsRef<[u8]> for TestParameterCursor<'a>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a> Read for TestParameterCursor<'a>

fn read(&mut self, buf: &mut [u8]) -> ParseResult<usize>

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).

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

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.

fn read_u64(&mut self) -> Result<u64, ParseError>

Read a u64 in little-endian format.

fn read_u32(&mut self) -> Result<u32, ParseError>

Read a u32 in little-endian format.

fn read_u16(&mut self) -> Result<u16, ParseError>

Read a u16 in little-endian format.

fn read_u8(&mut self) -> Result<u8, ParseError>

Read a u8.

fn read_i64(&mut self) -> Result<i64, ParseError>

Read a i64 in little-endian format.

fn read_i32(&mut self) -> Result<i32, ParseError>

Read a i32 in little-endian format.

fn read_i16(&mut self) -> Result<i16, ParseError>

Read a i16 in little-endian format.

fn read_i8(&mut self) -> Result<i8, ParseError>

Read a i32 in little-endian format.

fn read_array<const N: usize>(&mut self) -> Result<[u8; N], ParseError>

Load an array of the given size.

impl<'a> Seek for TestParameterCursor<'a>

type Err = ()

fn seek(&mut self, seek: SeekFrom) -> Result<u32, Self::Err>

Seek to the new position. If successful, return the new position from the beginning of the stream.

fn cursor_position(&self) -> u32

Get the cursor position counted from the beginning of the stream.
