Struct JjCapabilities 

#[non_exhaustive]
pub struct JjCapabilities {
    pub version: JjVersion,
}

What the installed jj binary supports, probed via JjApi::capabilities. A value type — the client holds no state, so probe once and keep the result (callers cache it).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

version: JjVersion

The binary’s parsed version.

Implementations

impl JjCapabilities

pub fn is_supported(&self) -> bool

Whether the binary meets the validated floor (jj ≥ 0.38).

pub fn ensure_supported(&self) -> Result<()>

Error unless is_supported — a clear “needs jj ≥ 0.38, found 0.35.0” instead of a cryptic argv/template failure later.

Trait Implementations

impl Clone for JjCapabilities

fn clone(&self) -> JjCapabilities

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for JjCapabilities

impl Debug for JjCapabilities

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for JjCapabilities

impl PartialEq for JjCapabilities

fn eq(&self, other: &JjCapabilities) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
