Struct indradb_plugin_host::VersionInfo

pub struct VersionInfo {
    pub rustc: String,
    pub plugin_interface: u8,
}

Represents the rustc compiler version and the plugin interface version. When a plugin is loaded, the VersionInfo of the server is cross-referenced against the VersionInfo exported by the plugin. If they don’t match, the plugin fails.

The rustc version must match exactly because rust doesn’t expose a stable ABI, and there is a risk of it changing in any version. The plugin interface version is also exposed to allow for changes to the interface in the future. If the interface is changed, this value should be incremented.

Fields

rustc: String

The version of rustc used to compile. This must match because rust doesn’t expose a stable ABI, and there is a risk of it changing in any version.

plugin_interface: u8

The plugin interface version is also exposed to allow for changes to the interface in the future.

Trait Implementations

impl Debug for VersionInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for VersionInfo

fn default() -> Self

Returns the “default value” for a type.

impl Display for VersionInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<VersionInfo> for VersionInfo

fn eq(&self, other: &VersionInfo) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
