Module csx64::asm::expr [−][src]
Everything needed to handle expression trees.
The important types are Expr, which represents an expression tree, and SymbolTable, which is the special collection type used for evaluation.
Structs
| Expr | An expression. |
| SymbolTable | An appendonly map-like collection of defined symbols. |
Enums
| EvalError | The reason why an expression failed to be evaluated. |
| ExprData | Holds the information needed to create an instance of |
| IllegalReason | The specific reason why an illegal operation failed. |
| OP | The supported operations in an expr. |
| Value | |
| ValueType |
Constants
| FLOAT_PRECISION | Number of precision bits to use for floating point values. This is strictly larger than fpu precision (64) so that we can have nigh-perfect end-results from expr after truncating to 64. |
| INT_PRECISION | Maximum number of significant bits to use for integer values. Values exceeding this are hard errors. This should at least be high enough to compute full products of u64 and i64. |
