Struct RtValueCast

pub struct RtValueCast { /* private fields */ }

Just a utility helping to cast the RtValue to the specific type.

    use forester_rs::runtime::args::RtArgs;
    use forester_rs::runtime::context::{TreeContext, TreeContextRef};
 fn tick(args: RtArgs, ctx: TreeContextRef) {
     match args.first() {
        None => (),
        Some(v) => {
            let val = v.cast(ctx.clone()).str().unwrap().unwrap_or_default();
            println!("{val}");
        }
    }
}

Implementations

impl RtValueCast

pub fn with_ptr(self) -> RtResult<RtValue>

tries to convert the value to the given type but considers the value as a pointer to the value in BlackBoard

pub fn str(self) -> RtResult<Option<String>>

pub fn int(self) -> RtResult<Option<i64>>

pub fn bool(self) -> RtResult<Option<bool>>

pub fn float(self) -> RtResult<Option<f64>>

pub fn map_vec<Map, To>(self, map: Map) -> RtResult<Option<Vec<To>>>

where Map: Fn(RtValue) -> To,

tries to convert to vec and map each element

pub fn map_obj<Map, To>(self, map: Map) -> RtResult<Option<HashMap<String, To>>>

where Map: Fn((String, RtValue)) -> (String, To),

tries to convert obj to map
