Module code_block_utils 

Utility functions for detecting and handling code blocks and code spans in Markdown for rumdl.

Code block detection is delegated to pulldown-cmark, which correctly implements the CommonMark specification. This handles edge cases like:

• Backtick fences with backticks in the info string (invalid per spec)
• Nested fences (longer fence contains shorter fence as content)
• Mixed fence types (tilde fence contains backticks as content)
• Indented code blocks with proper list context handling

Structs

CodeBlockDetail

Detailed information about a code block captured during parsing

CodeBlockUtils

Utility functions for detecting and handling code blocks in Markdown

ColonDefinitionDetail

ParseResult

Structure facts from document analysis, capturing data needed by individual rules.

Enums

CodeBlockContext

Functions

continued_depth

How many of the containers in enclosing (outermost first) line continues: the longest prefix of enclosing that strip_enclosure accepts.

strip_enclosure

Remove the prefixes the containers in enclosing (outermost first) put on line, or None when the line does not continue all of them.

Type Aliases

LineToListMap

Ordered list membership: maps line number (1-indexed) to list ID

ListStartValues

Ordered list start values: maps list ID to the start value
