Enum AdaptiveBuffer 

pub enum AdaptiveBuffer {
    Memory(Vec<u8>),
    File(LargeBuffer),
}

Adaptive buffer that switches between in-memory and file-backed storage.

Variants

Memory(Vec<u8>)

In-memory buffer for small data.

File(LargeBuffer)

File-backed buffer for large data.

Implementations

impl AdaptiveBuffer

pub const fn new() -> Self

Create a new adaptive buffer.

pub const fn with_threshold(_threshold: usize) -> Self

Create a new adaptive buffer with a custom threshold.

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

Append data to the buffer.

Errors

Returns an error if file operations fail when using file-backed storage.

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 const fn is_file_backed(&self) -> bool

Check if the buffer is using file-backed storage.

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

Read all data from the buffer.

Errors

Returns an error if file operations fail.

pub fn tail(&mut self, n: usize) -> Result<Vec<u8>>

Read the last N bytes.

Errors

Returns an error if file operations fail.

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

Clear the buffer.

Errors

Returns an error if file operations fail.

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

Get the data as a string (lossy UTF-8).

Errors

Returns an error if file operations fail.
