PropertyValue

Struct PropertyValue

pub struct PropertyValue(/* private fields */);

Expand description

A newtype wrapper that can be used to construct [NodePropertyValue]-compatible values for crate::NodeBuilder::add_property, and to read the values of the properties reported by crate::DriverContext::node_properties.

Implementations§

impl PropertyValue

pub fn from_string(value: impl Into<String>) -> Self

Creates a value from something that is string-like

pub fn from_int(value: impl Into<u32>) -> Self

Creates a value from something that is integer-like

pub fn from_bool(value: impl Into<bool>) -> Self

Creates a value from something that is bool-like

pub fn as_int(&self) -> Option<u32>

Returns the value if it is an integer property.

pub fn as_str(&self) -> Option<&str>

Returns the value if it is a string property.

pub fn as_bool(&self) -> Option<bool>

Returns the value if it is a boolean property.

pub fn as_enum(&self) -> Option<&str>

Returns the value if it is an enum property.
