Struct dharitri_wasm::types::BoxedBytes

pub struct BoxedBytes(/* private fields */);

Simple wrapper around a boxed byte slice, but with a lot of optimized methods for manipulating it. The focus is on reducing code size rather improving speed.

Implementations

impl BoxedBytes

pub fn empty() -> Self

pub fn zeros(len: usize) -> Self

pub unsafe fn allocate(len: usize) -> Self

Allocates an uninitialized BoxedBytes to heap.

Safety

Should only be called if the contents are initialized immediately afterwards, e.g. via a FFI call.

pub fn as_ptr(&self) -> *const u8

pub fn as_mut_ptr(&mut self) -> *mut u8

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn into_box(self) -> Box<[u8]>

pub fn as_slice(&self) -> &[u8]

pub fn from_concat(slices: &[&[u8]]) -> Self

Create new instance by concatenating several byte slices.

pub fn split(self, at: usize) -> (BoxedBytes, BoxedBytes)

Splits BoxedBytes into 2 others at designated position. Returns the original and an empty BoxedBytes if position arugment out of range.

Trait Implementations

impl AsRef<[u8]> for BoxedBytes

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

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

impl Clone for BoxedBytes

fn clone(&self) -> BoxedBytes

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BoxedBytes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> From<&'a [u8]> for BoxedBytes

fn from(byte_slice: &'a [u8]) -> Self

Converts to this type from the input type.

impl From<Box<[u8]>> for BoxedBytes

fn from(b: Box<[u8]>) -> Self

Converts to this type from the input type.

impl From<BoxedBytes> for SCError

fn from(boxed_bytes: BoxedBytes) -> Self

Converts to this type from the input type.

impl From<BoxedBytes> for TokenIdentifier

fn from(boxed_bytes: BoxedBytes) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for BoxedBytes

fn from(v: Vec<u8>) -> Self

Converts to this type from the input type.

impl NestedDecode for BoxedBytes

fn dep_decode<I: NestedDecodeInput>(input: &mut I) -> Result<Self, DecodeError>

Attempt to deserialise the value from input, using the format of an object nested inside another structure. In case of success returns the deserialized value and the number of bytes consumed during the operation.

fn dep_decode_or_exit<I: NestedDecodeInput, ExitCtx: Clone>( input: &mut I, c: ExitCtx, exit: fn(_: ExitCtx, _: DecodeError) -> ! ) -> Self

Version of top_decode that exits quickly in case of error. Its purpose is to create smaller implementations in cases where the application is supposed to exit directly on decode error.

impl NestedEncode for BoxedBytes

fn dep_encode<O: NestedEncodeOutput>( &self, dest: &mut O ) -> Result<(), EncodeError>

NestedEncode to output, using the format of an object nested inside another structure. Does not provide compact version.

fn dep_encode_or_exit<O: NestedEncodeOutput, ExitCtx: Clone>( &self, dest: &mut O, c: ExitCtx, exit: fn(_: ExitCtx, _: EncodeError) -> ! )

Version of top_decode that exits quickly in case of error. Its purpose is to create smaller implementations in cases where the application is supposed to exit directly on decode error.

impl PartialEq for BoxedBytes

fn eq(&self, other: &BoxedBytes) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TopDecode for BoxedBytes

fn top_decode<I: TopDecodeInput>(input: I) -> Result<Self, DecodeError>

Attempt to deserialize the value from input.

fn top_decode_or_exit<I: TopDecodeInput, ExitCtx: Clone>( input: I, _: ExitCtx, _: fn(_: ExitCtx, _: DecodeError) -> ! ) -> Self

Version of top_decode that exits quickly in case of error. Its purpose is to create smaller implementations in cases where the application is supposed to exit directly on decode error.

impl TopEncode for BoxedBytes

fn top_encode<O: TopEncodeOutput>(&self, output: O) -> Result<(), EncodeError>

Attempt to serialize the value to ouput.

fn top_encode_or_exit<O: TopEncodeOutput, ExitCtx: Clone>( &self, output: O, _: ExitCtx, _: fn(_: ExitCtx, _: EncodeError) -> ! )

Version of top_decode that exits quickly in case of error. Its purpose is to create smaller bytecode implementations in cases where the application is supposed to exit directly on decode error.

impl TopEncodeOutput for &mut BoxedBytes

This allows us to use a mutable BoxedBytes as top encode output.

fn set_slice_u8(self, bytes: &[u8])

fn set_u64(self, value: u64)

fn set_i64(self, value: i64)

impl TypeAbi for BoxedBytes

fn type_name() -> String

fn provide_type_descriptions<TDC: TypeDescriptionContainer>( accumulator: &mut TDC )

A type can provide more than its own description. For instance, a struct can also provide the descriptions of the type of its fields. TypeAbi doesn’t care for the exact accumulator type, which is abstracted by the TypeDescriptionContainer trait.
