Struct DspConfigDescriptor 

pub struct DspConfigDescriptor { /* private fields */ }

Citizen descriptor for a DSP processor configuration: a kind name plus a list of named f64 parameters.

The configuration is stored in its Expr encoding so it round-trips through the citizen protocol.

Implementations

impl DspConfigDescriptor

pub fn new(kind: impl Into<String>, params: Vec<(String, f64)>) -> Result<Self>

Builds a config descriptor, validating the kind and parameters.

pub fn gain(gain: f64) -> Result<Self>

Builds a gain config descriptor with a single gain parameter.

pub fn from_expr(expr: Expr) -> Result<Self>

Builds a descriptor from a config expression, validating that it decodes.

pub fn kind(&self) -> Result<String>

Decodes and returns the config kind name.

pub fn params(&self) -> Result<Vec<(String, f64)>>

Decodes and returns the config parameters as name/value pairs.

pub fn as_expr(&self) -> &Expr

Returns the underlying config expression without decoding it.
