Module asm 

EVM bytecode assembler.

Structs

Inst 🔒

A parsed instruction.

MacroDef 🔒

A macro definition: parameter names and body tokens.

Token 🔒

A token produced by the tokenizer.

Tokenizer 🔒

Character-by-character tokenizer over source text.

Enums

Imm 🔒

An immediate value.

Item 🔒

A parsed item from the source.

PushKind 🔒

How the push width is determined.

TokenKind 🔒

The kind of a Token.

Functions

builtin_macros 🔒

Builtin macros available in all assembly sources.

emit_inst_no_labels 🔒

Emit a single instruction (no-label fast path).

encode_imm 🔒

Encode a U256 as big-endian bytes with optional fixed size.

expand_macros 🔒

Expand macro invocations in a token stream.

expect_imm 🔒

Consume the next token as an immediate (number or label ref).

expect_number_u8 🔒

Consume the next token as a number and convert to u8.

layout_and_emit 🔒

Layout items with label resolution (fixed-point for auto-sized label pushes) and emit bytecode.

min_push_width 🔒

Compute the minimum push width for a value (0 for zero, 1 for 1..=0xff, etc.).

parse_asm

Parse EVM assembly from a string into bytecode.

parse_define 🔒

Parse a #define directive body (everything after #define) into the macro table.

parse_items 🔒

Parse a token stream into items.

preprocess 🔒

Preprocess source text: extract #define directives (line-scoped), tokenize the rest, then expand macro invocations on the token stream.

resolve_imm 🔒

Resolve an immediate value, substituting label PCs.
