Enum Status 

pub enum Status {
    Unparsed,
    Expanded,
    Done,
    Failed,
}

Lifecycle state of a node in a ParseTree.

Variants

Unparsed

The node is waiting to be processed by the pass scheduled for its round.

Expanded

The pass expanded the node; its children carry the remaining work.

Done

The pass accepted the node as fully parsed; it has no children.

Failed

The pass that processed the node could not parse it.

A failed node is retried once per remaining pass in the schedule; once every pass has had a turn the failure is permanent. Kept in the tree so consumers (e.g. an LSP) still see the coarse structure around errors.

Implementations

impl Status

pub fn is_unparsed(self) -> bool

Returns true if the status is Status::Unparsed.

pub fn is_failed(self) -> bool

Returns true if the status is Status::Failed.

Trait Implementations

impl Clone for Status

fn clone(&self) -> Status

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Status

impl Debug for Status

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

Formats the value using the given formatter.

impl Eq for Status

impl Hash for Status

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for Status

fn cmp(&self, other: &Status) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Status

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Status

fn partial_cmp(&self, other: &Status) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
