Struct Trigger 

pub struct Trigger {
    pub name: String,
    pub target: TraceRef,
    pub enabled: bool,
    pub level: f64,
    pub slope: TriggerSlope,
    pub single_shot: bool,
    pub trigger_position: f64,
    pub look: TraceLook,
    pub holdoff_secs: f64,
    /* private fields */
}

A trigger configuration for oscilloscope-style capture.

Triggers detect when a signal crosses a specified level in a given direction (rising, falling, or any). They can operate in single-shot mode (capture once then stop) or auto mode (continuously re-arm after each trigger).

Fields

name: String

User-facing name for this trigger

target: TraceRef

The trace to monitor for trigger crossings

enabled: bool

Whether this trigger is enabled

level: f64

The threshold level to detect crossings at

slope: TriggerSlope

Which edge direction(s) to trigger on

single_shot: bool

If true, trigger once and stop; if false, continuously re-arm

trigger_position: f64

Position in buffer where trigger should appear (0.0 = left edge, 1.0 = right edge)

look: TraceLook

Visual appearance for the trigger level line

holdoff_secs: f64

Holdoff time in seconds. After a trigger fires, the next trigger will not fire until at least this much time has passed. Default: 0.0.

Implementations

impl Trigger

pub fn reset(&mut self)

Reset the trigger state, clearing any pending or completed trigger.

pub fn reset_runtime_state(&mut self)

Full reset including the start flag.

pub fn start(&mut self)

Arm the trigger to start looking for crossings.

pub fn stop(&mut self)

Stop the trigger from looking for crossings.

pub fn get_info(&self, axis: &AxisSettings) -> String

Short, user-facing description used in UI and legend labels. Example: “trace1: rising @ 1.23 V, pos 0.50, single”

pub fn get_info_without_slope(&self, axis: &AxisSettings) -> String

Like get_info but without the slope word, so the caller can render an icon in its place. Example: “trace1: @ 1.23 V • Single”

pub fn slope_icon(&self) -> EdgeIcon

Returns the edge icon corresponding to the trigger slope.

pub fn last_trigger_time(&self) -> Option<f64>

Last trigger timestamp (seconds) if a crossing was detected since reset.

pub fn is_triggered(&self) -> bool

Returns true if a trigger has fired and is enabled.

pub fn is_active(&self) -> bool

Returns true if the trigger is armed and actively looking for crossings.

pub fn is_trigger_pending(&self) -> bool

Returns true if a trigger crossing was detected but we’re waiting for more samples.

pub fn check_trigger(&mut self, data: &mut LivePlotData<'_>) -> bool

Check the target trace for a trigger crossing and optionally pause after a configurable number of subsequent samples. trigger_position is in [0,1]:

• 0.0 => pause immediately when the trigger occurs
• 1.0 => pause after data.max_points new samples on the target trace Values in between scale linearly.

Returns true if there’s an active trigger pending or just fired.

Trait Implementations

impl Default for Trigger

fn default() -> Self

Returns the “default value” for a type.
