Struct ConditionParser 

pub struct ConditionParser;

Parser for AHB condition expressions.

Implementations

impl ConditionParser

pub fn parse(input: &str) -> Result<Option<ConditionExpr>, ParseError>

Parse an AHB status string into a condition expression.

Returns Ok(None) if the input contains no condition references (e.g., bare "Muss" or empty string).

Examples

use automapper_validation::expr::ConditionParser;
use automapper_validation::expr::ConditionExpr;

let expr = ConditionParser::parse("Muss [494]").unwrap().unwrap();
assert_eq!(expr, ConditionExpr::Ref(494));

pub fn parse_with_ub( input: &str, ub_definitions: &BTreeMap<String, ConditionExpr>, ) -> Result<Option<ConditionExpr>, ParseError>

Parse an AHB status string, expanding UB condition references inline.

When [UB1] is encountered and ub_definitions contains “UB1”, the corresponding pre-parsed expression is substituted. Unknown UB references fall back to the normal parse_condition_id behavior.

pub fn parse_status_branches( input: &str, ub_definitions: &BTreeMap<String, ConditionExpr>, ) -> Result<Vec<StatusBranch>, ParseError>

Parse an AHB status into one StatusBranch per status line.

Validation asks for the same few hundred statuses of a format version for every field of every group instance (an MSCONS Lastgang: thousands of times each), so each thread keeps what it parsed. A status naming a UB condition depends on ub_definitions as well and is not kept.

pub fn parse_raw(input: &str) -> Result<Option<ConditionExpr>, ParseError>

Parse an expression that is known to contain conditions (no prefix stripping).

Returns Err if the input cannot be parsed. Returns Ok(None) if empty.
