Struct dharitri_wasm::types::ManagedBufferNestedDecodeInput

pub struct ManagedBufferNestedDecodeInput<M, MB>
where
    M: ManagedTypeApi,
    MB: Borrow<ManagedBuffer<M>>,
{
    pub managed_buffer: MB,
    pub decode_index: usize,
    pub buffer_len: usize,
    /* private fields */
}

Nested decode buffer based on a managed buffer. Uses the load/copy slice API to extract pieces of the managed buffer for deserialization.

Fields

managed_buffer: MB

decode_index: usize

buffer_len: usize

fn remaining_len(&self) -> usize

The remaining length of the input data.

fn read_into(&mut self, into: &mut [u8]) -> Result<(), DecodeError>

Read the exact number of bytes required to fill the given buffer.

fn read_into_or_exit<ExitCtx: Clone>( &mut self, into: &mut [u8], c: ExitCtx, exit: fn(_: ExitCtx, _: DecodeError) -> ! )

Read the exact number of bytes required to fill the given buffer. Exit early if there are not enough bytes to fill the result.

fn read_specialized<T, C, F>( &mut self, context: C, else_deser: F ) -> Result<T, DecodeError>

where T: TryStaticCast, C: TryStaticCast, F: FnOnce(&mut Self) -> Result<T, DecodeError>,

fn read_specialized_or_exit<T, C, ExitCtx, F>( &mut self, context: C, c: ExitCtx, exit: fn(_: ExitCtx, _: DecodeError) -> !, else_deser: F ) -> T

where T: TryStaticCast, C: TryStaticCast, F: FnOnce(&mut Self, ExitCtx) -> T, ExitCtx: Clone,

fn is_depleted(&self) -> bool

True if all data from the buffer has already been used.

fn read_byte(&mut self) -> Result<u8, DecodeError>

Read a single byte from the input.

fn read_byte_or_exit<ExitCtx>( &mut self, c: ExitCtx, exit: fn(_: ExitCtx, _: DecodeError) -> ! ) -> u8

where ExitCtx: Clone,

Read a single byte from the input.
