Struct gix_url::Url

pub struct Url {
    pub scheme: Scheme,
    pub port: Option<u16>,
    pub path: BString,
    /* private fields */
}

A URL with support for specialized git related capabilities.

Additionally there is support for deserialization and serialization.

Security Warning

URLs may contain passwords and using standard formatting will redact such password, whereas lossless serialization will contain all parts of the URL. Beware that some URls still print secrets if they use them outside of the designated password fields.

Also note that URLs that fail to parse are typically stored in the resulting error type and printed in full using its display implementation.

Fields

scheme: Scheme

The URL scheme.

port: Option<u16>

The port to use when connecting to a host. If None, standard ports depending on scheme will be used.

path: BString

The path portion of the URL, usually the location of the git repository.

Security-Warning

URLs allow paths to start with - which makes it possible to mask command-line arguments as path which then leads to the invocation of programs from an attacker controlled URL. See https://secure.phabricator.com/T12961 for details.

If this value is going to be used in a command-line application, call Self::path_argument_safe() instead.

Implementations

impl Url

Instantiation

pub fn from_parts( scheme: Scheme, user: Option<String>, password: Option<String>, host: Option<String>, port: Option<u16>, path: BString, serialize_alternative_form: bool ) -> Result<Self, Error>

Create a new instance from the given parts, including a password, which will be validated by parsing them back.

impl Url

Modification

pub fn set_user(&mut self, user: Option<String>) -> Option<String>

Set the given user, or unset it with None. Return the previous value.

pub fn set_password(&mut self, password: Option<String>) -> Option<String>

Set the given password, or unset it with None. Return the previous value.

impl Url

Builder

pub fn serialize_alternate_form(self, use_alternate_form: bool) -> Self

Enable alternate serialization for this url, e.g. file:///path becomes /path.

This is automatically set correctly for parsed URLs, but can be set here for urls created by constructor.

pub fn canonicalize(&mut self, current_dir: &Path) -> Result<(), Error>

Turn a file url like file://relative into file:///root/relative, hence it assures the url’s path component is absolute, using current_dir if needed to achieve that.

impl Url

Access

pub fn user(&self) -> Option<&str>

Returns the user mentioned in the url, if present.

pub fn password(&self) -> Option<&str>

Returns the password mentioned in the url, if present.

pub fn host(&self) -> Option<&str>

Returns the host mentioned in the url, if present.

Security-Warning

URLs allow hosts to start with - which makes it possible to mask command-line arguments as host which then leads to the invocation of programs from an attacker controlled URL. See https://secure.phabricator.com/T12961 for details.

If this value is going to be used in a command-line application, call Self::host_argument_safe() instead.

pub fn host_argument_safe(&self) -> Option<&str>

Return the host of this URL if present and if it can’t be mistaken for a command-line argument.

Use this method if the host is going to be passed to a command-line application.

pub fn path_argument_safe(&self) -> Option<&BStr>

Return the path of this URL and if it can’t be mistaken for a command-line argument. Note that it always begins with a slash, which is ignored for this comparison.

Use this method if the path is going to be passed to a command-line application.

pub fn path_is_root(&self) -> bool

Returns true if the path portion of the url is /.

pub fn port_or_default(&self) -> Option<u16>

Returns the actual or default port for use according to the url scheme. Note that there may be no default port either.

impl Url

Transformation

pub fn canonicalized(&self, current_dir: &Path) -> Result<Self, Error>

Turn a file url like file://relative into file:///root/relative, hence it assures the url’s path component is absolute, using current_dir if necessary.

impl Url

Serialization

pub fn write_to(&self, out: &mut dyn Write) -> Result<()>

Write this URL losslessly to out, ready to be parsed again.

pub fn to_bstring(&self) -> BString

Transform ourselves into a binary string, losslessly, or fail if the URL is malformed due to host or user parts being incorrect.

impl Url

Deserialization

pub fn from_bytes(bytes: &BStr) -> Result<Self, Error>

Parse a URL from bytes
