[−][src]Struct parquet::memory::BufferPtr
An representation of a slice on a reference-counting and read-only byte array. Sub-slices can be further created from this. The byte array will be released when all slices are dropped.
Methods
impl<T> BufferPtr<T>[src]
impl<T> BufferPtr<T>pub fn new(v: Vec<T>) -> Self[src]
pub fn new(v: Vec<T>) -> SelfCreates new buffer from a vector.
pub fn data(&self) -> &[T][src]
pub fn data(&self) -> &[T]Returns slice of data in this buffer.
pub fn with_range(self, start: usize, len: usize) -> Self[src]
pub fn with_range(self, start: usize, len: usize) -> SelfUpdates this buffer with new start position and length len.
Range should be within current start position and length.
pub fn with_mem_tracker(self, mc: MemTrackerPtr) -> Self[src]
pub fn with_mem_tracker(self, mc: MemTrackerPtr) -> SelfAdds memory tracker to this buffer.
pub fn start(&self) -> usize[src]
pub fn start(&self) -> usizeReturns start position of this buffer.
pub fn len(&self) -> usize[src]
pub fn len(&self) -> usizeReturns length of this buffer
pub fn is_mem_tracked(&self) -> bool[src]
pub fn is_mem_tracked(&self) -> boolReturns true if this buffer has memory tracker, false otherwise.
pub fn all(&self) -> BufferPtr<T>[src]
pub fn all(&self) -> BufferPtr<T>Returns a shallow copy of the buffer. Reference counted pointer to the data is copied.
pub fn start_from(&self, start: usize) -> BufferPtr<T>[src]
pub fn start_from(&self, start: usize) -> BufferPtr<T>Returns a shallow copy of the buffer that starts with start position.
pub fn range(&self, start: usize, len: usize) -> BufferPtr<T>[src]
pub fn range(&self, start: usize, len: usize) -> BufferPtr<T>Returns a shallow copy that is a range slice within this buffer.

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?
Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S is the encoder/decoder state type, T is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
