Struct DatabaseQuery 

pub struct DatabaseQuery {
    pub time_start: Option<f64>,
    pub time_end: Option<f64>,
    pub name_prefix: Option<String>,
    pub param_filter: Option<(String, String)>,
}

Query predicate for filtering SimulationRecord entries.

Fields

time_start: Option<f64>

Keep only records whose timestamp >= this value.

time_end: Option<f64>

Keep only records whose timestamp <= this value.

name_prefix: Option<String>

Keep only records whose name starts with this prefix.

param_filter: Option<(String, String)>

Keep only records that have param key equal to value.

pub fn with_param(self, key: impl Into<String>, val: impl Into<String>) -> Self

Filter by a parameter key=value match.

pub fn matches(&self, rec: &SimulationRecord) -> bool

Check whether a SimulationRecord passes this query.
