Struct FrameRecord 

pub struct FrameRecord {
    pub snapshot: String,
    pub lines: Vec<String>,
}

Snapshot of a single rendered frame, captured by TestBackend::record_frames.

Stores the styled snapshot string (via Buffer::snapshot_format) plus a per-row trimmed text view for ergonomic substring assertions. Both are produced from the same buffer and are guaranteed to refer to the same frame.

Cheap to clone; useful for replaying a failing test by inspecting intermediate frames.

Fields

snapshot: String

Styled snapshot of the buffer at this frame, in the stable Buffer::snapshot_format vocabulary.

lines: Vec<String>

Plain-text view of each buffer row, trailing spaces trimmed. Mirrors TestBackend::line for every row.

Implementations

impl FrameRecord

pub fn to_string_trimmed(&self) -> String

Return the frame as a multi-line string (rows joined with \n, trailing empty rows preserved). Mirrors TestBackend::to_string_trimmed on the originating buffer.

pub fn line(&self, y: u32) -> &str

Return the trimmed text of row y from this frame, or empty if y is past the buffer height.

pub fn assert_contains(&self, expected: &str)

Assert any row in this frame contains expected. Panics with a row-by-row dump on failure.

Trait Implementations

impl Clone for FrameRecord

fn clone(&self) -> FrameRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameRecord

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

Formats the value using the given formatter.

impl PartialEq for FrameRecord

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