Implementations

impl<'a> ActionParameterBuilder<'a>

pub fn new(name: &'a str, description: &'a str) -> Self

pub fn add_possible_variable(self, possible_variable: &str) -> Self

The name of the variables that can be used to compute the value of the parameter. For example for the start value of a seek action, we will accept to take ‘duration’ which will be replace by the total duration of the stream on which the action is executed.

pub fn add_possible_variable_if( self, possible_variable: &str, predicate: bool, ) -> Self

pub fn add_possible_variable_if_some( self, possible_variable: Option<&str>, ) -> Self

pub fn mandatory(self) -> Self

pub fn default_value(self, default_value: &'a str) -> Self

pub fn default_value_if(self, default_value: &'a str, predicate: bool) -> Self

pub fn default_value_if_some(self, default_value: Option<&'a str>) -> Self

pub fn add_type(self, types: &str) -> Self

The types the parameter can take described as a string.

NOTE: The types should end with (GstClockTime) if its final type is a GstClockTime, this way it will be processed when preparing the actions.
