Crate giga_segy_out 

This is a simplified library for writing SEG-Y files from rust. It is designed purely for writing SEG-Y files in a trace by trace manner and supports writing with different settings and sample coordinate formats.

The library was designed to follow the SEG Technial Standards Committee’s SEG-Y_r2.0 standard (from January 2017).

This library is not designed for editing of SEG-Y files, although it can theoretically be accomplished with the clever use of giga_segy_in. However we do not recommend this.

Modules

create_headers

This module contains the traits for creating new instances of headers.

enums

This contains all the enums that are used in the trace and binary headers.

utils

This module contains the CoordinateScalar structure which deals with the somewhat unusual way that SEG-Y uses to express scaling factor of coordinates.

write_data

This contains the code for writing the data to the file.

write_headers

This submodule exists for converting headers to bytes and writing them.

Structs

BinHeader

This structure represents a parsed binary header for a SEG-Y file.

ReadableTapeLabel

This is a rust readable version of the TapeLabel structure, which can be generated after the file has been read, but is not stored.

SegyFile

A structure which represents a mapped SEG-Y file. This represents a writeable SEG-Y.

SegyMetadata

This structure contains all of the metadata for opening a SEG-Y file.

SegySettings

This structure holds a list of various settings to be imported for the custom reading of byte locations of various variables in the headers and other things when interpreting a SEG-Y file.

TapeLabel

This structure represents the 128-byte SEG-Y tape label which is largely optional. It appears that this is stored mostly as character bytes (u8).

Trace

This structure represents a SEG-Y trace.

TraceCoordinates

This structure gives several different ways of looking at trace coordinates. It is created once a trace has been written and moved into the SegyFile lookup.

TraceHeader

This structure represents a parsed binary trace header for a single trace of a SEG-Y file..

Enums

RsgError

Basic Error types.
