Struct Lv2Port 

pub struct Lv2Port {
    pub index: u32,
    pub symbol: String,
    pub name: String,
    pub kind: Lv2PortKind,
    pub dir: PortDir,
    pub channels: u16,
}

One declared port of an Lv2PluginDescriptor.

Carries the LV2 port metadata and lowers to a graph PortDecl via Lv2Port::to_port_decl.

Fields

index: u32

The LV2 port index within its plugin.

symbol: String

The LV2 port symbol, used as the graph port name.

name: String

The human-readable port name.

kind: Lv2PortKind

The LV2 port class.

dir: PortDir

The signal direction (input or output).

channels: u16

The number of graph lanes (channels) this port exposes.

Implementations

impl Lv2Port

pub fn new( index: u32, symbol: impl Into<String>, name: impl Into<String>, kind: Lv2PortKind, dir: PortDir, channels: u16, ) -> Result<Self>

Builds a port from its fields, validating symbol, name, and channels.

Errors

Returns Error::Eval when symbol or name is blank, or when channels is zero.

pub fn audio_input( index: u32, symbol: impl Into<String>, channels: u16, ) -> Result<Self>

Builds an audio input port named “Audio Input” with channels lanes.

Errors

Returns Error::Eval when symbol is blank or channels is zero.

pub fn audio_output( index: u32, symbol: impl Into<String>, channels: u16, ) -> Result<Self>

Builds an audio output port named “Audio Output” with channels lanes.

Errors

Returns Error::Eval when symbol is blank or channels is zero.

pub fn control_input( index: u32, symbol: impl Into<String>, name: impl Into<String>, ) -> Result<Self>

Builds a single-lane control input port with the given name.

Errors

Returns Error::Eval when symbol or name is blank.

pub fn atom_input(index: u32, symbol: impl Into<String>) -> Result<Self>

Builds a single-lane atom-sequence input port named “Events In”.

Errors

Returns Error::Eval when symbol is blank.

pub fn to_port_decl(&self) -> PortDecl

Lowers this port to a graph PortDecl.

Trait Implementations

impl Clone for Lv2Port

fn clone(&self) -> Lv2Port

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Lv2Port

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Lv2Port

impl PartialEq for Lv2Port

fn eq(&self, other: &Lv2Port) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
