Crate ailloli_ui_devtools_core

Backend-agnostic DevTools snapshots, warnings, picking, and wire messages.

Snapshot geometry uses logical pixels and stable numeric element IDs. The collector walks retained children in tree order; picking walks the flattened snapshot in reverse so later, deeper paint candidates win. Warning geometry comparisons tolerate half a logical pixel.

Structs

DebugColor

Serializable floating-point RGBA color.

DebugConstraints

Serializable min/max layout constraints in logical pixels.

DebugFlexItem

Serializable flex-item inputs attached to a retained child.

DebugLayoutInfo

Optional layout-pass inputs and measured output for one element.

DebugLayoutSizeHint

Serializable width/height hints exposed by a retained element.

DebugNode

Flattened retained-tree node with layout, clip, style, and warning diagnostics.

DebugOffset

Serializable logical translation.

DebugPoint

Serializable point in logical viewport coordinates.

DebugRect

Serializable logical-pixel rectangle.

DebugSize

Serializable logical width and height.

DebugSlot

Parent-assigned child slot in local and absolute logical coordinates.

DebugSnapshot

Serializable snapshot of one retained subtree and its derived diagnostics.

DebugWarning

Human-readable diagnostic optionally attributed to one node.

TerminalDebugSnapshot

Terminal snapshot plus deterministic cell identities for DevTools inspection.

Enums

DebugDrawCmd

Backend-neutral overlay primitive derived from hover, selection, or warnings.

DebugLength

Serializable declarative length used by size hints and flex basis.

DebugWarningKind

Stable warning categories emitted by compute_warnings.

DevToolsClientMessage

Tagged client-to-host DevTools protocol message.

DevToolsMode

Requested DevTools presentation mode.

DevToolsServerMessage

Tagged host-to-client DevTools protocol message.

Functions

collect_debug_snapshot

Collects a subtree with no selected/hovered state at frame index zero.

collect_debug_snapshot_with_state

Collects a pre-order subtree and derives warnings with explicit host state.

compute_warnings

Replaces snapshot-wide and per-node derived warning lists.

debug_draw_cmds

Builds hover, selection, then warning outlines in deterministic order.

pick_element_at

Returns the topmost laid-out node containing a logical viewport point.

terminal_debug_snapshot

Captures terminal state with config and adds deterministic cell identities.
