Crate Mem_Parser 

Zero-copy semi-structured log parsing: streaming lines plus optional arena AST.

mmap safety

See MappedFile.

Structs

ArenaParser

Parses lines into bump-allocated ASTs. Combine with Bump::reset between lines for cheap rollback of speculative work.

BorrowedRecord

One parsed line with zero-copy field references into the source.

FieldNode

FieldRef

Zero-copy key/value or value-only field.

LineAst

AST for a single line; field slice memory is owned by the arena ('arena).

LineIter

Iterator over logical lines in buf, validated as UTF-8 per line.

LineView

One line of text with its starting byte offset in the parent buffer.

LogDialect

Configurable delimiters for semi-structured logs.

LogStream

Stream BorrowedRecord values from a contiguous byte buffer (UTF-8 validated per line).

MappedFile

Read-only mmap of an entire file, owning the memmap2::Mmap handle.

Span

Inclusive-exclusive byte span into UTF-8 source text [start, end).

Enums

ParseError

Source

Convenience holder for contiguous input (mmap vs caller-owned/borrowed string).

SplitMode

How to split field tokens on a line.

Functions

fields_on_line

Collect key/value or space-token fields from one line (heap Vec per call).

lines_in_str

Stream all lines from a UTF-8 &str (no per-line mmap cost beyond validation).

parse_log_stream

Convenience: stream from a guaranteed UTF-8 &str (same bytes as src.as_bytes()).

push_fields_on_line

Bump-friendly: push fields into out without extra allocation beyond out growth.
