Crate neopdf_capi 

The C-language interface for NeoPDF

Structs

NeoPDFGrid

An opaque struct holding the data for a single grid, including its subgrids and flavors. C code should not access its fields directly.

NeoPDFGridArrayCollection

Represents a dynamically-sized collection of NeoPDFGrid pointers. This struct is exposed to C and manages memory for the array of pointers.

NeoPDFLazyIterator

Opaque pointer to a lazy PDF iterator object.

NeoPDFMembers

Structure to hold an array of PDF pointers and its length.

NeoPDFMetaData

Metadata for PDF grids

NeoPDFMetaDataV2

Metadata for PDF grids (V2 with extended fields)

NeoPDFPhysicsParameters

Physical Parameters of the PDF set.

NeoPDFWrapper

Opaque pointer to a PDF object.

Enums

NeopdfResult

Result codes for NeoPDF operations

NeopdfSubgridParams

Parameters for subgrids in the PDF grid.
