Struct Def 

pub struct Def<CTX: Context> { /* private fields */ }

Process definition.

Implementations

impl<CTX: Context> Def<CTX>

pub fn define( id: CTX::PID, kind: Kind, sourcepoints: Vec<CTX::CID>, endpoints: Vec<CTX::CID>, ) -> Result<Self, Vec<DefineError>>

The only method to create a valid process def struct. Checks for duplicate sourcepoints or endpoints, self-loops, and restrictions on process kind (asynchronous processes are incompatible with certain combinations of backends).

Errors

Duplicate sourcepoint:

let result = process::Def::<Mycontext>::define (
  ProcessId::A,
  process::Kind::isochronous_default(),
  vec![ChannelId::X, ChannelId::Z, ChannelId::X],
  vec![ChannelId::Y]);
assert_eq!(
  result, Err (vec![process::DefineError::DuplicateSourcepoint]));

Duplicate endpoint:

let result = process::Def::<Mycontext>::define (
  ProcessId::A,
  process::Kind::isochronous_default(),
  vec![ChannelId::X, ChannelId::Z],
  vec![ChannelId::Y, ChannelId::Y]);
assert_eq!(
  result, Err (vec![process::DefineError::DuplicateEndpoint]));

Self-loop:

let result = process::Def::<Mycontext>::define (
  ProcessId::A,
  process::Kind::isochronous_default(),
  vec![ChannelId::X, ChannelId::Z],
  vec![ChannelId::Y, ChannelId::Z]);
assert_eq!(
  result, Err (vec![process::DefineError::SourcepointEqEndpoint]));

Asynchronous process zero endpoints:

let result = process::Def::<Mycontext>::define (
  ProcessId::A,
  process::Kind::asynchronous_default(),
  vec![ChannelId::Z],
  vec![]);
assert_eq!(
  result,
  Err (vec![process::DefineError::AsynchronousZeroEndpoints]));

Asynchronous process multiple endpoints:

let result = process::Def::<Mycontext>::define (
  ProcessId::A,
  process::Kind::asynchronous_default(),
  vec![ChannelId::Z],
  vec![ChannelId::X, ChannelId::Y]);
assert_eq!(
  result,
  Err (vec![process::DefineError::AsynchronousMultipleEndpoints]));

Trait Implementations

impl<CTX: Clone + Context> Clone for Def<CTX>

where CTX::PID: Clone, CTX::CID: Clone,

fn clone(&self) -> Def<CTX>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<CTX: Debug + Context> Debug for Def<CTX>

where CTX::PID: Debug, CTX::CID: Debug,

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

Formats the value using the given formatter.

impl<CTX: PartialEq + Context> PartialEq for Def<CTX>

where CTX::PID: PartialEq, CTX::CID: PartialEq,

fn eq(&self, other: &Def<CTX>) -> 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.
