Struct EqInfo 

#[non_exhaustive]
pub struct EqInfo {
    pub band_count: u8,
    pub db_range: u8,
    pub capabilities: EqCapabilities,
    pub db_min: i8,
    pub db_max: i8,
}

EQ table information from get_eq_info.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

band_count: u8

Number of frequency bands.

db_range: u8

Gain range in dB; used as ±db_range when db_min/db_max are both 0.

capabilities: EqCapabilities

How EQ values are stored.

db_min: i8

Minimum gain in dB, or 0 to imply -db_range.

db_max: i8

Maximum gain in dB, or 0 to imply +db_range.

Implementations

impl EqInfo

pub fn effective_range(&self) -> (i8, i8)

The effective (min, max) gain range in dB.

Resolves the “both zero implies ±db_range” rule into concrete bounds.
