Struct BlockIdentifier 

pub struct BlockIdentifier(usize);

The TX-2 Users Handbook describes a section of source code beginning with an optional origin as a “block”. See, for example section 6-2.5 and section 6-3.4 (specifically, page 6-23).

This is not the same way in which “block” is used in more modern programming languages (for example, C), where a block is normally associated with a scope. While TX-2’s assembler does have scopes (in macro bodies) these are are a concept.

We assign blocks unique identifiers, which are values of type BlockIdentifier.

Implementations

impl BlockIdentifier

pub fn previous_block(self) -> Option<BlockIdentifier>

Trait Implementations

impl Clone for BlockIdentifier

fn clone(&self) -> BlockIdentifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockIdentifier

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

Formats the value using the given formatter.

impl Display for BlockIdentifier

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

Formats the value using the given formatter.

impl From<BlockIdentifier> for usize

fn from(value: BlockIdentifier) -> usize

Converts to this type from the input type.

impl From<usize> for BlockIdentifier

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Ord for BlockIdentifier

fn cmp(&self, other: &BlockIdentifier) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for BlockIdentifier

fn eq(&self, other: &BlockIdentifier) -> 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.

impl PartialOrd for BlockIdentifier

fn partial_cmp(&self, other: &BlockIdentifier) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
