EnginePrepareInfo
Namespace: E2E.Engine
public sealed record EnginePrepareInfo : IEquatable<EnginePrepareInfo>The facts handed to an engine’s prepare (CancellationToken)), once per run and target in the runner
process, before any worker exists. Upstream’s EnginePrepareInfo.
Inheritance: object
Implements: IEquatable<EnginePrepareInfo>
Properties
Section titled “Properties”public required IReadOnlyDictionary<string, string?> Env { get; init; }The run’s environment: what every worker is started with. A host may hand the run an environment other than the process’s own, so anything provisioned here that a worker later looks up by environment must be resolved against this, not the process environment.
Value: IReadOnlyDictionary<string, string>
public required Action<string> Log { get; init; }Reports one line of progress. A run streams it as a notice to the reporter; the standalone host of e2e explore and
e2e mcp has no reporter, so it drops the line.
Value: Action<string>
ProjectRoot
Section titled “ProjectRoot”public string? ProjectRoot { get; init; }The directory relative paths in the config resolve against: where an engine resolves a relative option, such as a build to install.
Null leaves it to the working directory. Upstream’s projectRoot.
Value: string
public required string RunId { get; init; }The run id.
Value: string
public required int Slots { get; init; }The worker slots the run will start for this target, 0 to Slots minus one. Provision for exactly these slots
(boot that many devices of a pool); the workers then find them ready. A standalone attempt, as e2e explore and
e2e mcp open, prepares one slot.
Value: int
TargetName
Section titled “TargetName”public required string TargetName { get; init; }The target being prepared.
Value: string
