Struct ContentLengthReader 

pub struct ContentLengthReader<'a> { /* private fields */ }

Reads a body with a known Content-Length.

This reader validates that exactly length bytes are provided and enforces the configured size limit.

Implementations

impl<'a> ContentLengthReader<'a>

pub fn new( buffer: &'a [u8], length: usize, config: &BodyConfig, ) -> Result<Self, BodyError>

Create a new Content-Length reader.

Arguments

• buffer - The buffer containing body bytes
• length - The Content-Length value
• config - Body reading configuration

Errors

Returns BodyError::TooLarge if length exceeds the configured maximum.

pub fn length(&self) -> usize

Returns the expected body length.

pub fn remaining(&self) -> usize

Returns the number of bytes remaining.

pub fn is_complete(&self) -> bool

Returns true if all bytes have been read.

pub fn read(&mut self, dest: &mut [u8]) -> Result<usize, BodyError>

Read up to max_bytes into the provided buffer.

Returns the number of bytes read.

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

Read all remaining body bytes.

Errors

Returns BodyError::Incomplete if the buffer doesn’t contain enough data.

pub fn read_all_borrowed(&self) -> Result<&'a [u8], BodyError>

Read all remaining body bytes as a borrowed slice.

This is zero-copy when the entire body is already in the buffer.

Errors

Returns BodyError::Incomplete if the buffer doesn’t contain enough data.

fn fmt(&self, f: &mut Formatter<'_>) -> Result
