Implementations§
§impl NullBuilder
impl NullBuilder
pub fn new() -> NullBuilder
pub fn new() -> NullBuilder
Creates a new null builder
pub fn with_capacity(_capacity: usize) -> NullBuilder
👎Deprecated: there is no actual notion of capacity in the NullBuilder, so emulating it makes little sense
pub fn with_capacity(_capacity: usize) -> NullBuilder
Creates a new null builder with space for capacity
elements without re-allocating
pub fn capacity(&self) -> usize
👎Deprecated: there is no actual notion of capacity in the NullBuilder, so emulating it makes little sense
pub fn capacity(&self) -> usize
Returns the capacity of this builder measured in slots of type T
pub fn append_null(&mut self)
pub fn append_null(&mut self)
Appends a null slot into the builder
pub fn append_nulls(&mut self, n: usize)
pub fn append_nulls(&mut self, n: usize)
Appends n
null
s into the builder.
pub fn append_empty_value(&mut self)
pub fn append_empty_value(&mut self)
Appends a null slot into the builder
pub fn append_empty_values(&mut self, n: usize)
pub fn append_empty_values(&mut self, n: usize)
Appends n
null
s into the builder.
pub fn finish_cloned(&self) -> NullArray
pub fn finish_cloned(&self) -> NullArray
Builds the NullArray without resetting the builder.
