Enum Operation 

pub enum Operation {
    CreateDataLink {
        pack: String,
        handler: String,
        source: PathBuf,
    },
    CreateUserLink {
        pack: String,
        handler: String,
        datastore_path: PathBuf,
        user_path: PathBuf,
    },
    RunCommand {
        pack: String,
        handler: String,
        executable: String,
        arguments: Vec<String>,
        sentinel: String,
    },
    CheckSentinel {
        pack: String,
        handler: String,
        sentinel: String,
    },
}

The four atomic operations dodot performs.

Uses enum variants with associated data so that each variant carries exactly the fields it needs — impossible states are unrepresentable.

Variants

CreateDataLink

Link a source file into the datastore. handler_data_dir(pack, handler) / filename -> source

Fields

pack: String

handler: String

source: PathBuf

CreateUserLink

Create a user-visible symlink. user_path -> datastore_path

Fields

pack: String

handler: String

datastore_path: PathBuf

user_path: PathBuf

RunCommand

Execute a command and record a sentinel on success.

Fields

pack: String

handler: String

executable: String

arguments: Vec<String>

sentinel: String

CheckSentinel

Check whether a sentinel exists (query, not mutation).

Fields

pack: String

handler: String

sentinel: String

Implementations

impl Operation

pub fn pack(&self) -> &str

pub fn handler(&self) -> &str

pub fn kind(&self) -> &'static str

Human-readable label for the operation type.

Trait Implementations

impl Clone for Operation

fn clone(&self) -> Operation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Operation

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

Formats the value using the given formatter.

impl Serialize for Operation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
