Struct Limits 

pub struct Limits {
    pub max_depth: u32,
    pub max_objects: u32,
    pub max_decoded_size: u64,
    pub max_compression_ratio: u64,
    pub ratio_floor: u64,
    pub max_xref_sections: u32,
    pub max_object_size: u64,
    pub max_pages: u32,
    pub budget: Option<Arc<dyn Budget>>,
}

Limits applied while reading. Every one is enforced; exceeding one is an error (crate::Error::Limit), never a panic or unbounded work.

Fields

max_depth: u32

Nesting depth of arrays and dictionaries within one object, and of reference chains followed while resolving.

max_objects: u32

Highest object number accepted from an xref section or a scan.

max_decoded_size: u64

Maximum decoded size of one stream, in bytes.

max_compression_ratio: u64

Maximum ratio of decoded to encoded size for one stream, applied once the output passes Limits::ratio_floor bytes.

ratio_floor: u64

Decoded size below which the ratio is not checked: small streams legitimately compress far better than large ones.

max_xref_sections: u32

Maximum number of xref sections followed through /Prev.

max_object_size: u64

Maximum size of one object’s syntax, excluding stream data.

max_pages: u32

Maximum number of pages enumerated.

budget: Option<Arc<dyn Budget>>

Optional CPU budget hook.

Implementations

impl Limits

pub fn charge(&self, units: u64) -> Result<(), Error>

Charges the CPU budget, if one is set.

Trait Implementations

impl Clone for Limits

fn clone(&self) -> Limits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Limits

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

Formats the value using the given formatter.

impl Default for Limits

fn default() -> Limits

Returns the “default value” for a type.
