Struct Pool 

pub struct Pool {
    pub identity: u64,
    pub packages: Vec<usize>,
    pub unacceptable_fixed_or_locked: Vec<usize>,
    pub warnings: Vec<String>,
    pub filter_list_removed: FilterListRemoved,
    /* private fields */
}

Fields

identity: u64

Pool identity (spl_object_id($pool) in Composer): the policy caches are keyed by pool.

packages: Vec<usize>

id - 1 -> arena index.

unacceptable_fixed_or_locked: Vec<usize>

warnings: Vec<String>

filter_list_removed: FilterListRemoved

filterListRemovedVersions: what a filter list removed (the rule generator and the solver consult it).

Implementations

impl Pool

pub fn new( packages: Vec<usize>, unacceptable: Vec<usize>, arena: &[Package], ) -> Pool

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn package_by_id(&self, id: usize) -> usize

packageById -> arena index.

pub fn id_of(&self, arena_idx: usize) -> Option<usize>

pub fn literal_to_package(&self, literal: i64) -> usize

pub fn what_provides( &self, arena: &[Package], name: &str, constraint: Option<&Constraint>, ) -> Vec<usize>

whatProvides -> pool ids.

pub fn matches( candidate: &Package, name: &str, constraint: Option<&Constraint>, ) -> bool

Pool::match.

pub fn is_filter_list_removed(&self, name: &str, version: &str) -> bool

isFilterListRemovedPackageVersion($name, Constraint('==', $version)).

pub fn with_packages(&self, kept: Vec<usize>, arena: &[Package]) -> Pool

The same pool reduced to kept (renumbered ids), removed versions and warnings preserved.

pub fn is_unacceptable_fixed_or_locked(&self, arena_idx: usize) -> bool

Trait Implementations

impl Clone for Pool

fn clone(&self) -> Pool

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pool

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

Formats the value using the given formatter.

impl Default for Pool

fn default() -> Pool

Returns the “default value” for a type.
