Struct dharitri_wasm::io::ArgDecodeInput

pub struct ArgDecodeInput<AA>
where
    AA: ManagedTypeApi + EndpointArgumentApi,
{ /* private fields */ }

Adapter from the API to the TopDecodeInput trait. Allows objects to be deserialized directly from the API as arguments.

Of course the implementation provides shortcut deserialization computation paths directly from API: into_u64, into_i64, …

This is a performance-critical struct. Since the wasm EndpointArgumentApi (VmApiImpl) is zero-size, it means that this structures translates to a single glorified i32 in wasm.

Implementations

impl<AA> ArgDecodeInput<AA>

where AA: ManagedTypeApi + EndpointArgumentApi,

pub fn new(api: AA, arg_index: i32) -> Self

Trait Implementations

impl<AA> TopDecodeInput for ArgDecodeInput<AA>

where AA: ManagedTypeApi + EndpointArgumentApi,

type NestedBuffer = ManagedBufferNestedDecodeInput<AA>

fn byte_len(&self) -> usize

Length of the underlying data, in bytes.

fn into_boxed_slice_u8(self) -> Box<[u8]>

Provides the underlying data as an owned byte slice box. Consumes the input object in the process.

fn into_u64(self) -> u64

Retrieves the underlying data as a pre-parsed u64. Expected to panic if the conversion is not possible.

fn into_i64(self) -> i64

Retrieves the underlying data as a pre-parsed i64. Expected to panic if the conversion is not possible.

fn into_specialized<T, F>(self, else_deser: F) -> Result<T, DecodeError>

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

fn into_nested_buffer(self) -> Self::NestedBuffer

fn into_specialized_or_exit<T, F, ExitCtx>( self, c: ExitCtx, exit: fn(_: ExitCtx, _: DecodeError) -> !, else_deser: F ) -> T

where T: TryStaticCast, ExitCtx: Clone, F: FnOnce(Self, ExitCtx, fn(_: ExitCtx, _: DecodeError) -> !) -> T,
