2.4 URI — Serd 0.32.4 documentation

# 2.4 URI

struct SerdURI

  A parsed URI.

  This struct directly refers to chunks in other strings, it does not own any memory itself. Thus, URIs can be parsed and/or resolved against a base URI in-place without allocating memory.

  SerdChunk scheme

    Scheme.

  SerdChunk authority

    Authority.

  SerdChunk path_base

    Path prefix if relative.

  SerdChunk path

    Path suffix.

  SerdChunk query

    Query.

  SerdChunk fragment

    Fragment.

uint8_t *serd_file_uri_parse(const uint8_t *uri, uint8_t **hostname)

  Get the unescaped path and hostname from a file URI.

  The returned path and `*hostname` must be freed with `serd_free()`.

  Parameters:

    - uri – A file URI.

    - hostname – If non-NULL, set to the hostname, if present.

  Returns:

    The path component of the URI.

SerdStatus serd_uri_parse(const uint8_t *utf8, SerdURI *out)

  Parse `utf8`, writing result to `out`

void serd_uri_resolve(const SerdURI *r, const SerdURI *base, SerdURI *t)

  Set target `t` to reference `r` resolved against `base`.

  See also: RFC3986 5.2.2

size_t serd_uri_serialise(const SerdURI *uri, SerdSink sink, void *stream)

  Serialise `uri` with a series of calls to `sink`

size_t serd_uri_serialise_relative(const SerdURI *uri, const SerdURI *base, const SerdURI *root, SerdSink sink, void *stream)

  Serialise `uri` relative to `base` with a series of calls to `sink`

  The `uri` is written as a relative URI iff if it a child of `base` and `root`. The optional `root` parameter must be a prefix of `base` and can be used keep up-references (“../”) within a certain namespace.

bool serd_uri_string_has_scheme(const uint8_t *utf8)

  Return true iff `utf8` starts with a valid URI scheme.
