manta-cli 2.0.0-beta.66

//! Implements the `manta config set site` command.
//!
//! Writes `site = "<name>"` to `cli.toml`. Server-side validation is
//! deferred until the next request that carries the `X-Manta-Site`
//! header — the CLI does not check the value locally.

/// Set the active site in configuration.
///
/// Consumes the clap matches for `config set site` (positional
/// `SITE_NAME`) and persists the value.
///
/// # Errors
///
/// Returns an error if the config file cannot be read or written, or
/// the renderer fails. The `SITE_NAME` positional is declared required
/// by clap, so its absence panics rather than returns.
