Struct BorrowedHeader

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

A zero-copy BorrowedRecord header.

Implementations

impl<'a> BorrowedHeader<'a>

pub fn new(key: &'a [u8], value: Option<&'a [u8]>) -> BorrowedHeader<'a>

Create a new header without any copies.

pub fn key(&self) -> &[u8]

Returns the header’s key.

pub fn value(&self) -> Option<&[u8]>

Returns the header’s value or None if there is no value.

pub fn to_owned(&self) -> RecordHeader

Clones this header obtaining ownership of the clone.

Trait Implementations

impl<'a> Clone for BorrowedHeader<'a>

fn clone(&self) -> BorrowedHeader<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for BorrowedHeader<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a BorrowedHeader<'a>> for BorrowedHeader<'a>

fn from(r: &'a BorrowedHeader<'_>) -> BorrowedHeader<'a>

Converts to this type from the input type.

impl<'a> From<&'a RecordHeader> for BorrowedHeader<'a>

fn from(header: &'a RecordHeader) -> BorrowedHeader<'a>

Converts to this type from the input type.

impl<'a> PartialEq for BorrowedHeader<'a>

fn eq(&self, other: &BorrowedHeader<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
