Struct TreePersistState 

pub struct TreePersistState {
    pub expanded_paths: HashSet<String>,
}

Stores the set of expanded node paths to restore tree expansion state.

Fields

expanded_paths: HashSet<String>

Set of expanded node paths (e.g., “root/src/main.rs”).

Trait Implementations

impl Clone for TreePersistState

fn clone(&self) -> TreePersistState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TreePersistState

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

Formats the value using the given formatter.

impl Default for TreePersistState

fn default() -> TreePersistState

Returns the “default value” for a type.

impl PartialEq for TreePersistState

fn eq(&self, other: &TreePersistState) -> 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.
