func BuildFromTemplate ¶

func BuildFromTemplate(
	template string,
	vars map[string]string,
	paramCodecs map[string]codex.Codec[string],
	wrapMissing func(name string) error,
	wrapErr func(name, value string, err error) error,
) (string, error)

from vars, validating each against the corresponding codec in paramCodecs. wrapMissing is called to produce a typed error when a template variable has no entry in vars. wrapErr is called to produce a typed error when codec validation fails.

func ParseTemplateVars ¶

func ParseTemplateVars(template string) map[string]bool

ParseTemplateVars returns the set of variable names (without braces) found in a path or topic template such as "/users/{id}/posts/{postId}".

func StripTemplateVars ¶ added in v0.5.0

func StripTemplateVars(template string) string

StripTemplateVars replaces each {varName} placeholder in template with the literal segment placeholder (the single character "x"). The result has the same structural shape as the template but contains no brace syntax.

This is used internally to make path/topic codec validation template-transparent: constraints run on the shape of the path/topic, not on the literal {varName} tokens.
