Struct dbus::Signature

pub struct Signature<'a>(_);

A wrapper around a string that is guaranteed to be a valid (single) D-Bus type signature. Supersedes TypeSig.

Methods

impl<'m> Signature<'m>

pub fn new<S: Into<Vec<u8>>>(s: S) -> Result<Signature<'m>, String>

Creates a new instance of this struct.

Note: If the no-string-validation feature is activated, this string will not be checked for conformance with the D-Bus specification.

pub fn from_slice(s: &'m [u8]) -> Result<Signature<'m>, String>

Creates a new instance of this struct. If you end it with \0, it can borrow the slice without extra allocation.

Note: If the no-string-validation feature is activated, this string will not be checked for conformance with the D-Bus specification.

pub unsafe fn from_slice_unchecked(s: &'m [u8]) -> Signature<'m>

This function creates a new instance of this struct, without checking. It's up to you to guarantee that s ends with a \0 and is valid.

pub fn as_cstr(&self) -> &CStr

View this struct as a CStr.

pub fn into_static(self) -> Signature<'static>

Makes sure this string does not contain borrows.

pub fn into_cstring(self) -> CString

Converts this struct to a CString.

impl Signature<'static>

pub fn make<A: Arg>() -> Signature<'static>

Makes a D-Bus signature that corresponds to A.

Trait Implementations

impl<'a> Arg for Signature<'a>
