VersionSelector

faucet_cli::serve::history::templates

Enum VersionSelector 

Source 
pub enum VersionSelector {
    Channel(VersionChannel),
    Pinned(u32),
}
Available on crate feature serve only.
Expand description

Which version of a template to use: a named VersionChannel or an exact number.

Omitting the selector is the same as stable, so a caller that never mentions versions rides the launched version — not whatever was registered most recently. Registering a nightly therefore moves nobody; only an explicit launch does.

Variants§

§

Channel(VersionChannel)

A named channel — stable (the default), another derived pointer, or a promoted environment.

§

Pinned(u32)

An exact version, for a pin or a rollback.

Implementations§

Source§

impl VersionSelector

Source

pub const fn stable() -> Self

The default selector: the launched version.

Source

pub const fn newest() -> Self

The highest registered version, launched or not.

Source

pub fn parse(raw: &str) -> CliResult<Self>

Parse a channel name or a positive integer. A numeric string is a pin; a name must be one of the closed channel set.

Source

pub fn is_stable(self) -> bool

True when this selector means “the launched version” — i.e. the default.

Source

pub fn pinned(self) -> Option<u32>

The exact version, when the selector already names one. Every channel — derived or assigned — needs a registry lookup, so callers must go through crate::templates::resolve_version rather than treating a None here as “the newest”.

Source

pub fn channel(self) -> Option<VersionChannel>

The channel this selector names, if any.
