Struct MirrorBuildOverride 

pub struct MirrorBuildOverride {
    pub command: Option<String>,
    pub render_command: Option<String>,
    pub env: BTreeMap<String, String>,
}

One component’s per-environment build override — the value type of MirrorConfig::build (R905).

Every field is additive-or-replacing against the component’s own workload.toml [build] table; an empty override is indistinguishable from declaring none.

Fields

command: Option<String>

Replaces build.command for this environment.

Absent leaves the workload’s own command in place — including absent, which means “this project has no external bundler step” and must keep meaning that (R838-B1). An override may therefore introduce a command where the workload’s [build] table declares none — a deliberate per-tier opt-in to a bundler, since the only way to write it is to name one. A workload with no [build] table at all is still skipped wholesale: there is no out_dir to publish from, so an override there would have nothing to hand the publish step.

render_command: Option<String>

Replaces build.render_command — the data-only re-render (revalidate_static). Overridden separately from command because the two run at different times against different inputs; a tier that needs a different bundler command usually needs the same renderer.

env: BTreeMap<String, String>

Environment variables exported to the build (and render) subprocess, applied on top of the inherited environment.

This is the knob for the common case — the command is the same, only a baked-in origin/flag differs — and it is what keeps a project from having to pre-declare one build:<env> script per environment before any environment can exist.

Implementations

impl MirrorBuildOverride

pub fn is_empty(&self) -> bool

true when this override would change nothing.

pub fn env_pairs(&self) -> Vec<(String, String)>

The override’s env table as the Vec<(String, String)> that both ExecContext::with_env and std::process::Command::envs want.
