Crate xinput_mapper 

Functional helpers to convert a DInput->XInput YAML mapping into an XInput-like state.

• Pure functions; no hidden global state
• YAML schema matches the one produced by dinput_mapper
• Comments are in English by request

Modules

XButtons

XInput button bit flags (matches Windows XINPUT header values)

Structs

Axes

Axis

Buttons

Device

Dpad

MappingYaml

TriggerDef

Triggers

XInputState

Minimal XInput-like state we produce.

Enums

LoadError

Distinguish IO vs YAML parse errors for file loading.

Functions

apply_anti_deadzone_i16

Optionally apply anti-deadzone (minimum magnitude). anti in [0..=32767].

apply_deadzone_i16

Apply a centered deadzone on an i16 axis. deadzone in [0..=32767]. Values within [-deadzone..deadzone] -> 0. Outside, linearly re-scale to full range to preserve reach.

apply_radial_deadzone

Radial deadzone for a stick. deadzone in [0..=32767].

autorepeat_fire

Auto-repeat helper: when a bit is held, fires at (first_delay_ms then repeat_rate_ms).

button_edges

Compute edge masks between previous and current buttons.

debounce_bit

Debounce mask: require a stable hold_count frames before accepting changes.

map_report_to_xinput

Convert a raw HID input report to an XInput-like state using the mapping. This is a pure function: output depends only on (mapping, report).

merge_masks

Merge a list of masks (e.g., macro/extra layers) into one via OR.

parse_mapping_yaml_file

Parse YAML file content into MappingYaml. Returns LoadError to separate IO and YAML failures.

parse_mapping_yaml_str

Parse YAML string into MappingYaml.

postprocess_stick

Compose helpers for a typical stick pipeline.

remap_buttons

Build a new mask by applying a remap table (source->dest). Missing sources are ignored. remap: list of (src_mask_bit, dst_mask_bit).

set_bit

Set/clear/toggle helpers

square_to_circle

Convert square stick into circular region while preserving direction.

toggle_bit

trigger_pressed

Trigger thresholding: turn trigger value [0..255] into boolean press.
