Struct Client 

pub struct Client { /* private fields */ }

The Linear API client.

Implementations

impl Client

pub fn from_token(token: impl Into<String>) -> Result<Self, LinearError>

Create a client with an explicit API token.

pub fn from_env() -> Result<Self, LinearError>

Create a client from the LINEAR_API_TOKEN environment variable.

pub fn from_file() -> Result<Self, LinearError>

Create a client from the ~/.linear_api_token file.

pub fn auto() -> Result<Self, LinearError>

Create a client by auto-detecting the token (env -> file).

pub async fn execute<T: DeserializeOwned>( &self, query: &str, variables: Value, data_path: &str, ) -> Result<T, LinearError>

Execute a GraphQL query and extract a single object from the response.

pub async fn execute_connection<T: DeserializeOwned>( &self, query: &str, variables: Value, data_path: &str, ) -> Result<Connection<T>, LinearError>

Execute a GraphQL query and extract a Connection from the response.

pub async fn query<T: DeserializeOwned + GraphQLFields>( &self, field: &str, ) -> Result<T, LinearError>

Execute a typed query using the type’s GraphQLFields implementation.

Builds the query from T::selection() — define a struct with only the fields you need for zero-overfetch queries.

#[derive(Deserialize)]
struct MyViewer { name: Option<String>, email: Option<String> }

impl GraphQLFields for MyViewer {
    fn selection() -> String { "name email".into() }
}

let me: MyViewer = client.query::<MyViewer>("viewer").await?;

pub async fn query_connection<T: DeserializeOwned + GraphQLFields>( &self, field: &str, ) -> Result<Connection<T>, LinearError>

Execute a typed connection query using the node type’s GraphQLFields implementation.

Builds { field { nodes { <T::selection()> } pageInfo { ... } } }.

impl Client

pub async fn download_url( &self, url: &str, ) -> Result<DownloadResult, LinearError>

Download a file from a URL.

Handles Linear’s signed/expiring CDN URLs (e.g. https://uploads.linear.app/...) as well as any other publicly accessible URL. Returns the raw bytes and content type so the caller can write them to disk or process them further.

Errors

Returns LinearError::HttpError if the server responds with a non-2xx status, or LinearError::Network if the request fails at the transport level.

Example

let client = lineark_sdk::Client::auto()?;
let result = client.download_url("https://uploads.linear.app/...").await?;
std::fs::write("output.png", &result.bytes).unwrap();

pub async fn upload_file( &self, filename: &str, content_type: &str, bytes: Vec<u8>, make_public: bool, ) -> Result<UploadResult, LinearError>

Upload a file to Linear’s cloud storage.

This is a two-step process:

1. Call the fileUpload GraphQL mutation to obtain a signed upload URL and required headers from Linear.
2. PUT the raw file bytes to that signed URL (a Google Cloud Storage endpoint).

On success, returns an UploadResult containing the permanent asset_url that can be referenced in issue descriptions, comments, or attachments.

Arguments

• filename — The original filename (e.g. "screenshot.png"). Linear uses this for display and content-type inference on its side.
• content_type — MIME type of the file (e.g. "image/png").
• bytes — The raw file content.
• make_public — If true, the uploaded file will be publicly accessible without authentication.

Errors

Returns an error if the fileUpload mutation fails, if the signed URL upload fails, or if the response is missing expected fields.

Example

let client = lineark_sdk::Client::auto()?;
let bytes = std::fs::read("screenshot.png").unwrap();
let result = client
    .upload_file("screenshot.png", "image/png", bytes, false)
    .await?;
println!("Uploaded to: {}", result.asset_url);
