Struct Limits 

#[non_exhaustive]
pub struct Limits {
    pub max_samples: u64,
    pub max_dimension: u32,
}

Safety limits applied while decoding untrusted input.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_samples: u64

Maximum number of samples (width * height * components) in a decoded image.

max_dimension: u32

Maximum image width or height.

Implementations

impl Limits

pub fn with_max_samples(self, max_samples: u64) -> Self

These limits with a different sample cap.

pub fn with_max_dimension(self, max_dimension: u32) -> Self

These limits with a different width/height cap.

pub fn check_dims(&self, width: u32, height: u32, cpp: u32) -> Result<()>

Check that an image of width × height × cpp samples is within the limits.

Trait Implementations

impl Clone for Limits

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Limits

impl Debug for Limits

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

Formats the value using the given formatter.

impl Default for Limits

fn default() -> Self

Returns the “default value” for a type.
