Struct AttachedUnit 

pub struct AttachedUnit {
    inner: RefCell<Box<dyn Unit>>,
    unit: Unsigned6Bit,
    pub is_input_unit: bool,
    pub connected: bool,
    pub in_maintenance: bool,
}

A unit which is known to the emulator (whether or not it is in “connected” mode).

Fields

inner: RefCell<Box<dyn Unit>>

unit: Unsigned6Bit

is_input_unit: bool

True for units which are input units. Some devices (Lincoln Writers for example) occupy two units, one for read (input) and the other for write (output).

connected: bool

in_maintenance: bool

Implementations

impl AttachedUnit

fn is_disconnected_output_unit(&self) -> bool

fn call_inner<A, F, T>( &self, what: &str, alarmer: &mut A, diagnostics: &CurrentInstructionDiagnostics, f: F, ) -> Result<T, Alarm>

where A: Alarmer, F: Fn(&dyn Unit) -> T,

Call function f on a unit, which must already be connected.

If the unit is not connected, calling this method is a bug.

fn call_mut_inner<A, F, T>( &self, what: &str, alarmer: &mut A, diagnostics: &CurrentInstructionDiagnostics, f: F, ) -> Result<T, Alarm>

where A: Alarmer, F: FnMut(&mut dyn Unit) -> T,

Call function f on a unit, which must already be connected.

If the unit is not connected, calling this method is a bug.

pub fn poll<A: Alarmer>( &self, ctx: &Context, _alarmer: &mut A, ) -> Result<UnitStatus, Alarm>

Query the status of an attached (but perhaps not connected) unit.

fn text_info(&self, ctx: &Context) -> String

Fetch a human-readable description of a unit (which may not be connected).

pub fn connect(&self, ctx: &Context, mode: Unsigned12Bit)

Connect an attached (and perhaps already connected) unit.

pub fn disconnect<A: Alarmer>( &self, ctx: &Context, _alarmer: &mut A, ) -> Result<(), Alarm>

Disconnect an attached unit, leaving it attached but not connected.

pub fn transfer_mode<A: Alarmer>( &self, alarmer: &mut A, diagnostics: &CurrentInstructionDiagnostics, ) -> Result<TransferMode, Alarm>

Query the TransferMode of a connected unit.

pub fn read<A: Alarmer>( &self, ctx: &Context, alarmer: &mut A, diagnostics: &CurrentInstructionDiagnostics, ) -> Result<MaskedWord, TransferFailed>

Perform a TSD for a connected input unit.

pub fn write( &mut self, ctx: &Context, source: Unsigned36Bit, diagnostics: &CurrentInstructionDiagnostics, ) -> Result<Option<OutputEvent>, TransferFailed>

Perform a TSD for a connected output unit.

pub fn on_input_event( &self, ctx: &Context, event: InputEvent, ) -> Result<InputFlagRaised, InputEventError>

Announce an input event for a connected unit.

pub fn name(&self) -> String

Query the name of an attached (but possibly not connected) unit.

Trait Implementations

impl Debug for AttachedUnit

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

Formats the value using the given formatter.
