Struct WindowLimit 

pub struct WindowLimit { /* private fields */ }

Accepted window headers and their maximum bit count.

This limits headers, not total output or allocated workspace. Use DecodeLimits to set those budgets. An extended header may declare a small window too; Self::standard rejects every extended header.

Examples

use mbrotli::WindowLimit;
let standard = WindowLimit::standard(24)?;
assert_eq!(standard.max_bits(), 24);
assert!(!standard.allows_large());
let extended = WindowLimit::large(24)?;
assert!(extended.allows_large());
assert!(WindowLimit::standard(25).is_err());

Implementations

impl WindowLimit

pub const fn standard(max_bits: u8) -> Result<Self, DecodeConfigError>

Accepts only RFC 7932 headers up to this bit count.

Errors

Returns an error unless max_bits is in 10..=24.

pub const fn large(max_bits: u8) -> Result<Self, DecodeConfigError>

Accepts standard and extended headers up to this bit count.

Errors

Returns an error unless max_bits is in 10..=62.

pub const fn max_bits(self) -> u8

Largest accepted window bit count.

pub const fn allows_large(self) -> bool

Whether extended headers are accepted, including those below 25 bits.
