Struct ExecutedInstruction 

pub struct ExecutedInstruction {
    pub source_line: String,
    pub produced_layer: bool,
    pub timestamp: DateTime<Utc>,
}

One executed Dockerfile instruction recorded in BuildSkeleton::instruction_log.

Task 4.D consumes this log to emit the OCI image config’s history array — one entry per source-line invocation, with empty_layer = true for config-only instructions (WORKDIR / ENV / etc.) and empty_layer = false for instructions that produced a real layer (FROM / RUN / COPY / ADD). The source_line field holds the reconstructed Dockerfile text (e.g. "FROM mcr.microsoft.com/...", "RUN choco install -y curl") so downstream tooling like docker history can render the build provenance.

Fields

source_line: String

Reconstructed Dockerfile source line for the instruction, used verbatim as the created_by value in the emitted OCI history entry. Reconstructed from the parsed instruction (rather than echoing the original line) so a Dockerfile with continuation backslashes or comments collapses to a single canonical form per instruction — which is what docker history displays.

produced_layer: bool

true when this instruction produced a real layer (FROM / RUN / COPY / ADD); false for config-only instructions. Determines the empty_layer field on the emitted OCI history entry.

timestamp: DateTime<Utc>

Build-time UTC timestamp captured at execution. Surfaces as created on the emitted OCI history entry.
