Struct ProjectionFingerprint 

#[non_exhaustive]
pub struct ProjectionFingerprint {
    pub workflow: WorkflowKey,
    pub version: WorkflowVersion,
    pub states: Vec<ProjectedShape>,
}

Everything one projector emits over a chosen set of states, at one version.

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.

workflow: WorkflowKey

The workflow this projector answers for.

version: WorkflowVersion

The version it declares, which is what the fingerprint is pinned to.

states: Vec<ProjectedShape>

One entry per state, in the order they were added.

Implementations

impl ProjectionFingerprint

pub fn of<W: WorkflowDefinition>(definition: &W) -> FingerprintBuilder<'_, W>

Starts a fingerprint for definition.

pub fn snapshot_name(&self) -> String

A snapshot name carrying the workflow and the version it pins.

Naming the snapshot after the version is the whole mechanism: a projector that changes without a bump fails against the file that already exists, and one that changes with a bump writes a new file beside the old, so the previous shape stays on record.
