Struct rustbus::wire::marshal::traits::SignatureBuffer

pub struct SignatureBuffer(_);

SignatureBuffer is used to store static or dynamic signatures and avoid allocations if possible. It is a wrapper around Cow.

Implementations

impl SignatureBuffer

pub fn new() -> Self

pub fn push_static(&mut self, sig: &'static str)

Pushes a &str into the signature buffer.

Avoids an allocation if the self was empty and was not allocated already, by storing the &'static str inside a Cow::Borrowed variant.

pub fn push_str(&mut self, sig: &str)

Pushes a &str into the signature buffer.

If sig has a 'static lifetime then SignatureBuffer::push_static should almost always be used instead of this, because it can provide a performance benefit by avoiding allocation.

pub fn to_string_mut(&mut self) -> &mut String

Return a &mut String which can be used to modify the signature.

Internally this is just a call to Cow::to_mut.

pub fn clear(&mut self)

Clear the signature.

If an allocation was already made it is retained for future use. If you wish to deallocate when clearing, then simply use SignatureBuffer::new.

pub fn from_string(sig: String) -> Self

pub fn as_str(&self) -> &str

pub fn truncate(&mut self, new_len: usize) -> Result<(), Error>
