Struct svgbob::Property [−][src]
pub struct Property {
pub ch: char,
pub behavior: Arc<dyn Fn(&Settings, &Property, &Property, &Property, &Property, &Property, &Property, &Property, &Property) -> Vec<(bool, Vec<Fragment>)> + Sync + Send>,

Fields
ch: char
behavior: Arc<dyn Fn(&Settings, &Property, &Property, &Property, &Property, &Property, &Property, &Property, &Property) -> Vec<(bool, Vec<Fragment>)> + Sync + Send>
behavior is the final output of fragments of the spot character depending on flag that is meet when checked agains the surrounding characters
Implementations
pub fn new(
ch: char,
signature: Vec<(Signal, Vec<Fragment>)>,
behavior: Arc<dyn Fn(&Settings, &Property, &Property, &Property, &Property, &Property, &Property, &Property, &Property) -> Vec<(bool, Vec<Fragment>)> + Sync + Send>
) -> Self
empty property serves as a substitue for None property for simplicity in the behavior code, never have to deal with Option
derive a strong property with a strong signal

The inverse inclusion map: attempts to construct self
from the equivalent element of its
superset. Read more
pub fn is_in_subset(&self) -> bool
pub fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
pub fn to_subset_unchecked(&self) -> SS
pub fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
pub fn from_subset(element: &SS) -> SP
pub fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
