Struct ToolchainConfig 

pub struct ToolchainConfig {
    pub htl: Option<String>,
}

[toolchain] — the htl command a project expects to be checked by.

Cargo.toml already pins the htl crate a Rust host builds against, and nothing pinned the command. The command is what decides whether the project checks: a default lint added in a release turns a green project red on unchanged sources, and without this key the first place that shows up is a teammate’s terminal rather than the line in this file that says which release the project moved to.

htl does not install anything — it is one binary, not a toolchain manager — so a mismatch is reported and the message names cargo install htl-cli.

Fields

htl: Option<String>

A Cargo-style requirement the running command must satisfy: "0.4" for 0.4.x, "1" for 1.x, ">=0.4.2, <0.6" when a project needs to say more. Absent, any command runs the project, which is what every project did before the key existed.

Implementations

impl ToolchainConfig

pub fn req(&self) -> Result<Option<VersionReq>>

The requirement, parsed. Ok(None) when the key is absent; Err when it is there and is not a requirement — which HtlConfig::parse raises with the rest of the config errors, so a typo here is found where a typo in [lint] is.
