Classes
struct	openswmmvis::io::ExportField
	One attribute column of an ExportTable. More...

struct	openswmmvis::io::ExportRow
	One feature: its coordinates and one value per field. More...

struct	openswmmvis::io::ExportTable
	One output layer (one SWMM object type, one mesh element kind). More...

struct	openswmmvis::io::ExportOptions
	Where and how to write. More...

struct	openswmmvis::io::ExportReport
	What happened. More...

struct	openswmmvis::io::VectorLayerSource
	A GIS vector or feature layer to export as it is. More...

Namespaces
namespace	openswmmvis

namespace	openswmmvis::io

Typedefs
using	openswmmvis::io::ExportProgress = std::function< bool(int done, int total, const QString &what)>

Enumerations
enum class	openswmmvis::io::ExportGeometry { openswmmvis::io::Point , openswmmvis::io::LineString , openswmmvis::io::Polygon }
	The one geometry kind of an exported table. More...

Functions
bool	openswmmvis::io::exportVectorTables (const QVector< ExportTable > &tables, const ExportOptions &options, const ExportProgress &progress, ExportReport *report)
	Write `tables` to `options.destination`.

bool	openswmmvis::io::exportVectorLayer (const VectorLayerSource &source, const ExportOptions &options, const ExportProgress &progress, ExportReport *report)
	Translate `source` into `options.destination`, reprojecting when `options.targetSrsWkt` is set. Same cancel and cleanup contract.

bool	openswmmvis::io::exportRaster (const QString &sourcePath, const QString &destination, const QString &targetSrsWkt, const ExportProgress &progress, ExportReport *report)
	Write raster `sourcePath` to GeoTIFF `destination`, warped to `targetSrsWkt` when it is set (plan Q10). Same contract.

QString	openswmmvis::io::exportPathFor (const ExportOptions &options, const QString &tableName)
	Compute a table output path using the curated format metadata.

QStringList	openswmmvis::io::shortFieldNames (const QStringList &names, int maxLen=10)
	Shapefile field names: at most `maxLen` characters and unique (case-insensitively), in order. "invertElev" stays; "surchargeDepth" becomes "surchargeD", a second one "surcharg_1".

Widget-free writer behind the layer tree's Export entries (workplans/FEATURE_LAYER_ROLES_AND_FIELDS_PLAN_2026-09-30.md §8.5, R8).

Collectors (io/swmmexport, io/meshexport) snapshot SWMM objects or mesh elements into openswmmvis::io::ExportTable values on the main thread. This module then builds them in an in-memory OGR dataset and lets one GDALVectorTranslate per destination do the format, the CRS transform and the creation options — so it touches no layer, engine or widget and runs on a worker. Vector and feature layers skip the collector: openswmmvis::io::exportVectorLayer re-opens their source by path, as every worker in this codebase does.

Contract shared with io/mesh2dresultsexport: progress may cancel at any point, and a cancelled or failed export deletes every file it created.
