Struct Index 

pub struct Index {
    pub schema: String,
    pub capability_floor: CanonVersion,
    pub releases: Vec<IndexEntry>,
}

The complete coverage ledger.

Fields

schema: String

Always INDEX_SCHEMA once parsed.

capability_floor: CanonVersion

The lowest release this ledger covers.

releases: Vec<IndexEntry>

One entry per covered release.

Implementations

impl Index

pub fn parse(bytes: &[u8]) -> Result<Self, GuidanceError>

Read the ledger.

Errors

GuidanceError for bytes that do not parse, a schema this engine does not read, or a release listed twice.

pub fn entry(&self, version: CanonVersion) -> Option<&IndexEntry>

What the ledger says about one release.

pub fn interval( &self, from: Option<CanonVersion>, to: CanonVersion, ) -> Vec<&IndexEntry>

Every release in the half-open interval, in order.
