Struct RunnerDownload 

pub struct RunnerDownload {
    pub os: String,
    pub architecture: String,
    pub download_url: String,
    pub filename: String,
    pub sha256_checksum: Option<String>,
}

One runner-package download GitHub publishes.

sha256_checksum is optional, and stays optional

It is optional in GitHub’s response schema, and this layer passes that through faithfully — as Option, never as an empty string and never as a default. e2 fails closed on its absence, requiring an operator-pinned digest rather than installing an unverified 150-300 MB package (05-infrastructure.md), and it can only do that if this layer does not paper the absence over.

Absent and empty are also kept apart. A missing field and a null both read as None; a field GitHub sent as "" reads as Some(""). Both are unusable as a digest, but they are different facts about GitHub’s response, and collapsing them would leave e2 unable to report which one it saw.

Fields

os: String

GitHub’s OS token: win, osx, linux.

architecture: String

GitHub’s architecture token: x64, arm64, arm.

download_url: String

filename: String

sha256_checksum: Option<String>

Implementations

impl RunnerDownload

pub fn matches(&self, os: Os, arch: Arch) -> bool

Whether this entry is the package for os/arch.

Both sides are parsed through the domain’s own Os and Arch, whose FromStr already accepts GitHub’s package tokens — win/osx/linux and x64/arm64/arm — because Os::label_token was chosen to be those very tokens. Comparing parsed values rather than strings is what keeps a windows/win spelling difference from silently matching nothing.

pub fn sha256_checksum(&self) -> Option<&str>

The published digest, if GitHub published one.
