Implementations

impl SignalValue

pub fn new(value: u64) -> SignalValue

Create a new SignalValue from an integer.

Example:

use dwfv::signaldb::SignalValue;
let mut value = SignalValue::new(0x42);

pub fn new_default(width: usize, value: BitValue) -> SignalValue

Create a new SignalValue with the same BitValue for every bit.

Example:

use dwfv::signaldb::{BitValue, SignalValue};
let mut value = SignalValue::new_default(16, BitValue::High);
assert_eq!(value, SignalValue::new(0xFFFF));

pub fn from_symbol_str(s: &str) -> SignalValue

Create a SignalValue from a symbol.

Example

use dwfv::signaldb::SignalValue;
let v = SignalValue::from_symbol_str("foo");
assert_eq!(v, SignalValue::Symbol("foo".to_string()));

pub fn from_hex(s: &str) -> SignalValue

Create a SignalValue from an hex string.

Example

use dwfv::signaldb::SignalValue;
let v = SignalValue::from_hex("2A");
assert_eq!(v, SignalValue::new(42));

pub fn invalid() -> SignalValue

Create an invalid SignalValue.

Example

use dwfv::signaldb::SignalValue;
let v = SignalValue::invalid();
assert_eq!(v.is_invalid(), true);

pub fn expand(&mut self, width: usize)

Expand the width of a SignalValue.

Example

use dwfv::signaldb::{BitValue, SignalValue};
let mut v = SignalValue::new_default(16, BitValue::High);
assert_eq!(v.width(), 16);
v.expand(32);
assert_eq!(v.width(), 32);
assert_eq!(v, SignalValue::new(0xFFFF));

pub fn width(&self) -> usize

Get the width of a SignalValue.

Example

use dwfv::signaldb::SignalValue;
let v = SignalValue::new(42);
assert_eq!(v.width(), 6);

pub fn is_invalid(&self) -> bool

Check if the SignalValue is invalid.

Example

See invalid.
