TemplateExpander

Struct TemplateExpander 

Source
pub struct TemplateExpander;
Expand description

Expands ${source.*} template references in a pipeline using resolved source data.

Implementations§

Source§

impl TemplateExpander

Source

pub fn expand( pipeline: &Pipeline, resolved: &HashMap<String, Value>, ) -> Pipeline

Expand all ${source.*} references in the pipeline’s vars and return an updated pipeline.

The pipeline’s vars values are expanded by replacing template expressions with data from the resolved map. Transformation fields containing templates are left in place (they are handled at apply-time, not here) since transformations use typed structures rather than raw strings.
