queries: List of named queries referenced by the formula

SloType

Values

exp_to_string

</>

pub fn exp_to_string(exp: parser.Exp) -> String

Converts an expression AST node to its string representation.

resolve_slo_query

</>

pub fn resolve_slo_query(
  value_expr: String,
  substitutions: dict.Dict(String, String),
) -> #(String, String)

Parse a value expression, resolve to GoodOverTotal primitive, substitute words, and return the numerator and denominator as strings. Panics if parsing or resolution fails.

resolve_slo_query_typed

</>

pub fn resolve_slo_query_typed(
  value_expr: String,
  substitutions: dict.Dict(String, String),
) -> Result(ResolvedSloQuery, String)

Parse a value expression, resolve to primitive, substitute words, and return the resolved SLO query type.

resolve_slo_to_hcl

</>

pub fn resolve_slo_to_hcl(
  value_expr: String,
  substitutions: dict.Dict(String, String),
) -> Result(ResolvedSloHcl, String)

Parse a value expression, resolve to primitive, substitute words, and return HCL blocks ready for Datadog terraform generation.
