Struct RootMarkers 

pub struct RootMarkers(pub Vec<Arc<str>>);

The ordered marker set a project root is recognised by.

Order is significant: the first marker present in a directory names the resulting [lattice_core::ProjectKind::Marker], so .git ahead of Cargo.toml means a repository that is also a crate reports .git.

Implementations

impl RootMarkers

pub fn markers(&self) -> &[Arc<str>]

The markers, in priority order.

pub fn to_vec(&self) -> Vec<String>

Owned Strings, the shape MarkerResolver::new takes.

Trait Implementations

impl Clone for RootMarkers

fn clone(&self) -> RootMarkers

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RootMarkers

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

Formats the value using the given formatter.

impl Default for RootMarkers

fn default() -> Self

Returns the “default value” for a type.

impl Eq for RootMarkers

impl OptionType for RootMarkers

fn enumerate() -> Option<Vec<&'static str>>

Open-ended: any filename can be a marker. The built-in set is offered as the completion starting point, which is also the value a user is most likely editing rather than replacing wholesale.

fn accepts_list() -> bool

A TOML array joins into this — see loader::apply_array.

fn parse(s: &str) -> Result<Self, String>

Parse the right-hand side of :set name=value. Errors are surfaced verbatim through the cmdline echo, so the message should read well to the user (mention valid forms when the space is finite). The parser MUST round-trip with format: T::parse(&v.format()) == Ok(v) for every v.

fn format(&self) -> String

Render the current value back to a string (:set foo? echo, the customize buffer view, value comparison). Round-trips with Self::parse.

fn type_label() -> &'static str

Short type label for :describe-option ("boolean", "foldmethod", etc.). Used in help bodies and the customize buffer view.

fn enumerate_with_docs() -> Option<Vec<EnumeratedValue>>

Optional: enumerate valid string forms WITH per-value doc strings for the cmdline-completion marginalia column. Default impl wraps Self::enumerate with empty docs; types with rich help override.

fn name_forms(_canonical: &str) -> Vec<String>

Optional: alternative name forms this type accepts for the option name itself. Used by completion to surface the name alongside its negation (:set nu / :set nonu). Default: no extra forms. Booleans return [format!("no{canonical}")].

fn is_bool() -> bool

Whether this type’s option supports :set noFOO. bool returns true; everything else false. Drives the negate path in the cmdline parser.

fn try_negation_value() -> Result<Self, String>

Negation value (only meaningful for Self::is_bool true). Default: returns Err – the registry guards by checking is_bool() first, so callers that respect the contract won’t observe this. The bool impl returns Ok(false).

fn enumerate_is_exhaustive() -> bool

Whether Self::enumerate is the COMPLETE set of valid values (a closed enum) or a completion hint over an open space.

fn schema() -> ConfigSchema

The declared shape of this type’s values.

fn to_value(&self) -> ConfigValue

This value as a schema-shaped tree.

fn from_value(value: &ConfigValue) -> Result<Self, String>

Rebuild from a tree. Default: the inverse of Self::to_value, deferring to parse so a type’s validation rules apply on this path exactly as they do on :set.

impl PartialEq for RootMarkers

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

Equality operator ==.

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

Inequality operator !=.
