[src]
impl BufferBuilderTrait<BooleanType> for BufferBuilder<BooleanType>
[src]
fn new(capacity: usize) -> Self
[src]
Creates a builder with a fixed initial capacity.
fn advance(&mut self, i: usize) -> Result<()>
[src]
fn append(&mut self, v: bool) -> Result<()>
[src]
Appends a value into the builder, growing the internal buffer as needed.
fn append_slice(&mut self, slice: &[bool]) -> Result<()>
[src]
Appends a slice of type T
, growing the internal buffer as needed.
fn reserve(&mut self, n: usize) -> Result<()>
[src]
Reserves memory for n
elements of type T
.
fn finish(&mut self) -> Buffer
[src]
Reset this builder and returns an immutable Buffer
.
