Struct SignatureBuf

pub struct SignatureBuf { /* private fields */ }

A D-Bus signature.

This is the owned variant which dereferences to Signature.

Implementations

impl SignatureBuf

pub const fn empty() -> SignatureBuf

Construct a new empty signature.

Examples

use tokio_dbus::SignatureBuf;

let sig = SignatureBuf::empty();
assert!(sig.is_empty());

pub const fn into_raw_parts(self) -> ([MaybeUninit<u8>; 256], usize)

Convert an owned signature into its raw parts.

pub const fn new_const(signature: &[u8]) -> SignatureBuf

Construct a new signature with validation inside of a constant context.

This will panic in case the signature is invalid.

use tokio_dbus::SignatureBuf;

const BAD: SignatureBuf = SignatureBuf::new_const(b"(a)");

Examples

use tokio_dbus::SignatureBuf;

const SIG: SignatureBuf = SignatureBuf::new_const(b"i(ai)");

pub fn new(signature: &[u8]) -> Result<SignatureBuf, SignatureError>

Try to construct a new signature with validation.

Trait Implementations

impl AsRef<Signature> for SignatureBuf

fn as_ref(&self) -> &Signature

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

impl Borrow<Signature> for SignatureBuf

fn borrow(&self) -> &Signature

Immutably borrows from an owned value.

impl Clone for SignatureBuf

fn clone(&self) -> SignatureBuf

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureBuf

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

Formats the value using the given formatter.

impl Deref for SignatureBuf

type Target = Signature

The resulting type after dereferencing.

fn deref(&self) -> &<SignatureBuf as Deref>::Target

Dereferences the value.

impl PartialEq<&Signature> for SignatureBuf

Equality check between a borrowed Signature and SignatureBuf.

Examples

use tokio_dbus::{Signature, SignatureBuf};

assert_eq!(SignatureBuf::empty(), *Signature::EMPTY);
assert_eq!(SignatureBuf::new(b"s")?, *Signature::STRING);

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialEq<Signature> for SignatureBuf

Equality check between Signature and SignatureBuf.

Examples

use tokio_dbus::{Signature, SignatureBuf};

assert_eq!(SignatureBuf::empty(), *Signature::EMPTY);
assert_eq!(SignatureBuf::new(b"s")?, *Signature::STRING);

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialEq<SignatureBuf> for &Signature

Equality check between SignatureBuf and a borrowed Signature.

Examples

use tokio_dbus::{Signature, SignatureBuf};

assert_eq!(Signature::EMPTY, SignatureBuf::empty());
assert_eq!(Signature::STRING, SignatureBuf::new(b"s")?);

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialEq<SignatureBuf> for Signature

Equality check between SignatureBuf and Signature.

Examples

use tokio_dbus::{Signature, SignatureBuf};

assert_eq!(*Signature::EMPTY, SignatureBuf::empty());
assert_eq!(*Signature::STRING, SignatureBuf::new(b"s")?);

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialEq for SignatureBuf

Equality check between SignatureBuf and SignatureBuf.

Examples

use tokio_dbus::{Signature, SignatureBuf};

assert_eq!(SignatureBuf::empty(), Signature::EMPTY.to_owned());
assert_eq!(SignatureBuf::new(b"s")?, Signature::STRING.to_owned());

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

Tests for self and other values to be equal, and is used by ==.

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

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