Struct zvariant::Signature

pub struct Signature(_);

String that identifies the type of an encoded value.

Methods

impl Signature

Create a new Signature.

pub fn as_str(&self) -> &str

The signature as a string.

Trait Implementations

impl Basic for Signature

Formats the value using the given formatter.

impl Decode for Signature

fn slice_data(
    data: impl Into<SharedData>,
    signature: impl Into<Signature>,
    _format: EncodingFormat
) -> Result<SharedData, VariantError>

Get the slice of data that belongs to implementing type.

fn decode(
    data: impl Into<SharedData>,
    signature: impl Into<Signature>,
    _format: EncodingFormat
) -> Result<Self, VariantError>

Decode instance of implementing type from the data slice.

fn take_from_variant(variant: Variant) -> Result<Self, VariantError>

Flatten the variant to enclosed value of the implementing type.

fn from_variant(variant: &Variant) -> Result<&Self, VariantError>

Flatten the variant reference to a reference of the enclosed value of the implementing type.

fn ensure_correct_signature(
    signature: impl Into<Signature>
) -> Result<Signature, VariantError>

Ensure given signature is correct and of the implementing type.

    signature: impl Into<Signature>
) -> Result<Signature, VariantError>

Get the slice of signature that belongs to implementing type.

fn slice_for_decoding(
    data: impl Into<SharedData>,
    signature: impl Into<Signature>,
    format: EncodingFormat
) -> Result<SharedData, VariantError>

A helper for [decode] implementation. Removes any leading padding bytes.

impl Deref for Signature

type Target = str

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Encode for Signature

const SIGNATURE_CHAR: char

The signature charachter of the implementing type.

const SIGNATURE_STR: &'static str

The signature charachter of the implementing type, in string format.

const ALIGNMENT: usize

The alignment required for encoding of the implementing type, as number of bytes.

fn encode_into(&self, bytes: &mut Vec<u8>, _format: EncodingFormat)

Encode self and append to the end of bytes buffer.

fn to_variant(self) -> Variant

Unflatten self into a [Variant].

fn is(variant: &Variant) -> bool

Checks if variant value is of the generic type T.

fn encode(&self, format: EncodingFormat) -> Vec<u8>

Encode self into a new byte buffer and return it.

fn signature(&self) -> Signature

Get the signature.

fn add_padding(bytes: &mut Vec<u8>, format: EncodingFormat)

Append required padding to bytes buffer.

fn padding(n_bytes_before: usize, _format: EncodingFormat) -> usize

The required padding for the implementing type.
