Struct ParamInfo 

pub struct ParamInfo {
    pub id: u32,
    pub name: &'static str,
    pub short_name: &'static str,
    pub group: &'static str,
    pub range: ParamRange,
    pub default_plain: f64,
    pub flags: ParamFlags,
    pub unit: ParamUnit,
    pub kind: ParamValueKind,
    pub midi_map: Option<MidiSource>,
    pub midi_channel: Option<u8>,
}

Metadata for a single parameter, used by format wrappers.

Copy because every field is POD (&'static str, scalars, bitflags, the ParamRange / ParamUnit enums). Lets the audio path pass param_infos[i] by value without clone() noise.

Fields

id: u32

name: &'static str

short_name: &'static str

group: &'static str

range: ParamRange

default_plain: f64

flags: ParamFlags

unit: ParamUnit

kind: ParamValueKind

Which *Param type backs this entry. Drives display rounding (IntParam skips fractional digits) and value_text parsing, independently of ParamRange - a FloatParam declared with range = "discrete(...)" should still format as a float, so inferring kind from range alone is wrong.

midi_map: Option<MidiSource>

Default host MIDI-learn binding: the MIDI message that should drive this parameter. None (the common case) means the host maps it itself with no plugin hint. Set by #[param(midi_cc = …)] / #[param(midi_source = …)]; read by the VST3 IMidiMapping, AU parameter-MIDI-mapping, and LV2 midi:binding paths. Ignored by CLAP / VST2 / AAX (the host owns the mapping).

midi_channel: Option<u8>

Optional channel scope for Self::midi_map, as the wire channel 0..=15. None matches any channel.
