Implementations

impl ArchivePolicy

pub const fn strict() -> ArchivePolicy

Returns a strict extraction-oriented policy.

pub const fn permissive() -> ArchivePolicy

Returns a permissive policy for trusted archive metadata.

pub const fn list_only() -> ArchivePolicy

Returns a policy suitable for listing-only workflows.

pub const fn with_max_entry_size(self, max_entry_size: u64) -> ArchivePolicy

Adds a maximum single entry size.

pub const fn with_max_total_size(self, max_total_size: u64) -> ArchivePolicy

Adds a maximum total known size.

pub const fn with_max_entries(self, max_entries: usize) -> ArchivePolicy

Adds a maximum entry count.

pub fn allows_path(&self, path: &str) -> bool

Returns whether a path is allowed by this policy.

pub fn entry_issues(&self, entry: &ArchiveEntry) -> Vec<ArchivePolicyIssue>

Returns policy issues for a single entry.

pub fn allows_entry(&self, entry: &ArchiveEntry) -> bool

Returns whether a single entry is allowed by this policy.

pub fn entries_issues( &self, entries: &[ArchiveEntry], ) -> Vec<ArchivePolicyIssue>

Returns policy issues for a complete entry listing.

pub fn allows_entries(&self, entries: &[ArchiveEntry]) -> bool

Returns whether a complete entry listing is allowed by this policy.

Trait Implementations

impl Clone for ArchivePolicy

fn clone(&self) -> ArchivePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArchivePolicy

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

Formats the value using the given formatter.

impl Default for ArchivePolicy

fn default() -> ArchivePolicy

Returns the “default value” for a type.

impl Hash for ArchivePolicy

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ArchivePolicy

fn cmp(&self, other: &ArchivePolicy) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ArchivePolicy

fn eq(&self, other: &ArchivePolicy) -> 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.

impl PartialOrd for ArchivePolicy

fn partial_cmp(&self, other: &ArchivePolicy) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
