Struct PreopenReport 

pub struct PreopenReport {
    pub artifact: String,
    pub role: String,
    pub scope: Option<String>,
    pub surface: PreopenSurface,
}

One artifact’s resolved WASI preopen as it appears in a ScopeReport — and therefore in mur run --explain-scope, in mur doctor, and in trace.jsonl’s session_start.effective_grants.

Per-artifact, like StateStoreReport beside it, and reported for the same reason: the capsule-wide ScopeReport::filesystem_scope is joined into no guest preopen root, so an operator reading that field alone learns nothing about what any tool, driver or hook can actually see.

Fields

artifact: String

The artifact whose entry in the capsule operator’s own manifest this describes.

role: String

murmur_artifact::ArtifactRuntime::as_str verbatim, so the report and the manifest name a role with one vocabulary.

scope: Option<String>

The entry’s declared capabilities.filesystem.scope, verbatim. None = undeclared, which is what Self::surface has already resolved against the role’s own baseline.

surface: PreopenSurface

What the guest is preopened into once the role’s baseline and Self::scope are both applied.

Implementations

impl PreopenReport

pub fn render(&self) -> String

The single line this preopen renders as, shared by ScopeReport::render and by mur doctor so the two cannot word the same grant differently.
