Struct BuildState 

pub struct BuildState {
    pub stages: Vec<StageState>,
    pub current_stage: usize,
    pub current_instruction: usize,
    pub output_lines: Vec<OutputLine>,
    pub scroll_offset: usize,
    pub completed: bool,
    pub error: Option<String>,
    pub image_id: Option<String>,
    pub total_stages: usize,
    pub total_instructions: usize,

Internal build state tracking

Fields

stages: Vec<StageState>

All stages in the build

current_stage: usize

Current stage index

current_instruction: usize

Current instruction index within the current stage

output_lines: Vec<OutputLine>

Output lines from the build process

scroll_offset: usize

Current scroll offset for output

completed: bool

Whether the build has completed

error: Option<String>

Error message if build failed

image_id: Option<String>

Final image ID if build succeeded

total_stages: usize

Total stages pre-declared by the backend via BuildEvent::BuildStarted.

Populated once up-front. Used by current_stage_display so the denominator is stable rather than growing as stages arrive. 0 means no backend pre-declaration was received; fall back to stages.len() in that case.

total_instructions: usize

Total instructions pre-declared by the backend via BuildEvent::BuildStarted.

Populated once up-front. Used by total_instructions so the progress-bar denominator is stable rather than growing as InstructionStarted events arrive. 0 means no backend pre-declaration was received; fall back to the event-sum.

Implementations

impl BuildState

pub fn total_instructions(&self) -> usize

Get the total number of instructions across all stages.

Prefers the pre-declared total from BuildEvent::BuildStarted (so the progress-bar denominator is stable); falls back to summing the stages we’ve learned about so far for older tests or backends that don’t emit BuildStarted.

pub fn completed_instructions(&self) -> usize

Get the number of completed instructions across all stages

pub fn current_stage_display(&self) -> String

Get a display string for the current stage

Trait Implementations

impl Debug for BuildState

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

Formats the value using the given formatter.

impl Default for BuildState

fn default() -> BuildState

Returns the “default value” for a type.
