Struct SpillBuffer 

pub struct SpillBuffer { /* private fields */ }

A buffer that can spill to disk for very large data sets.

Starts in memory and automatically spills to disk when the spill threshold is exceeded.

Implementations

impl SpillBuffer

pub fn new() -> Self

Create a new spill buffer with default configuration.

pub fn with_config(config: LargeBufferConfig) -> Self

Create a new spill buffer with custom configuration.

pub const fn is_spilled(&self) -> bool

Check if the buffer has spilled to disk.

pub const fn len(&self) -> usize

Get the current size of the buffer.

pub const fn is_empty(&self) -> bool

Check if the buffer is empty.

pub fn write(&mut self, data: &[u8]) -> Result<()>

Write data to the buffer.

Errors

Returns an error if disk I/O fails during spill.

pub fn read_all(&mut self) -> Result<Vec<u8>>

Read all data from the buffer.

Errors

Returns an error if disk I/O fails.

pub fn as_string(&mut self) -> Result<String>

Read as a string (lossy UTF-8 conversion).

Errors

pub fn clear(&mut self) -> Result<()>

Clear the buffer.

If spilled to disk, the file is truncated.
