Struct EnvironmentStore 

pub struct EnvironmentStore { /* private fields */ }

In-memory storage for global and session-local environment values.

Implementations

impl EnvironmentStore

pub fn new() -> Self

Creates an empty environment store with no implicit defaults.

pub fn is_empty(&self) -> bool

Returns whether neither global nor session-local values are present.

pub fn set(&mut self, scope: ScopeSelector, name: String, value: String)

Stores the given visible value in the selected scope.

pub fn set_with_flags( &mut self, scope: ScopeSelector, name: String, value: String, flags: u8, )

Stores the given value and flag word in the selected scope.

pub fn set_implicit_global(&mut self, name: String, value: String)

Stores an implicit global value captured from the server environment.

pub fn set_implicit_global_display(&mut self, name: String, value: String)

Stores an implicit global value that is only renderable by show-environment.

pub fn clear(&mut self, scope: ScopeSelector, name: String)

Clears the selected variable, leaving a tombstone entry behind.

pub fn unset(&mut self, scope: ScopeSelector, name: &str) -> bool

Removes the selected variable entirely.

pub fn contains_entry(&self, scope: &ScopeSelector, name: &str) -> bool

Returns whether the exact entry exists in the selected scope.

pub fn global_value(&self, name: &str) -> Option<&str>

Returns the exact global value for the given variable, when present and not cleared.

pub fn global_entries(&self) -> impl Iterator<Item = (&str, &str)>

Returns all exact global environment entries in unspecified order.

pub fn session_value( &self, session_name: &SessionName, name: &str, ) -> Option<&str>

Returns the exact session-local value for the given variable, when present and not cleared.

pub fn resolve( &self, session_name: Option<&SessionName>, name: &str, ) -> Option<&str>

Resolves a single variable using session-local then global lookup.

pub fn resolved(&self, session_name: &SessionName) -> HashMap<String, String>

Returns the visible explicit environment snapshot that future panes should inherit.

pub fn apply_to_process_environment( &self, session_name: Option<&SessionName>, values: &mut HashMap<String, String>, )

Applies the selected scope chain to a process environment map.

pub fn apply_to_process_environment_without_implicit_globals( &self, session_name: Option<&SessionName>, values: &mut HashMap<String, String>, )

Applies explicit values only, skipping implicit globals captured from the server process.

pub fn suppressed_process_environment_names( &self, session_name: Option<&SessionName>, include_implicit_globals: bool, ) -> HashSet<String>

Returns names that must be removed from raw process environments.

pub fn update( &mut self, session_name: &SessionName, patterns: &[String], source: &HashMap<String, String>, )

Merges client variables into a session environment using tmux update-environment.

pub fn show_environment_entries( &self, scope: &ScopeSelector, hidden_only: bool, name: Option<&str>, ) -> Result<Vec<ShowEnvironmentEntry>, RmuxError>

Returns sorted show-environment entries for the selected global or session scope.

pub fn remove_session( &mut self, session_name: &SessionName, ) -> Option<HashMap<String, String>>

Removes all session-local values for the given session.

pub fn rename_session( &mut self, session_name: &SessionName, new_name: SessionName, ) -> Result<(), RmuxError>

Rekeys all session-local values from one validated session name to another.
